You can either do a flasher module or relay old vehicles use relay and very simple switching new vehicles because apparently the clicking annoyed people. Now they use this all electric circuit. Vs simple relay but again both systems are easy to fix the flasher unit and relay have essentially the same job blink the circuit and the lever is a simple on off switch the parts that are sensitive to load are the flasher or relay and when handed a much lower load than expected causes them to switch faster because the amps they are getting are higher. So old vehicle get led relay new vehicle find the flashing unit and get a led ready one for your particular vehicle.

I certainly would suggest going back in and mounting those resistors directly to the sheet metal body panel nice and tight with screws. In fact, I'd recommend putting CPU thermal paste between the resistor and the sheet metal too. Those resistors get very hot. The heat sink fins are useless in there with no air flow. The 3M adhesive pad is insulating the resistor from a very convenient, HUGE heat sink which is the metal body panel. Paint or FluidFilm the screw points to rust proof them.

Theres no dedicated brake light on a 7-way trailer connector. There is a trailer brake wire ran off of the brake controller that provides higher voltage depending on settings on the controller. Your hitch plug light is connected to the right turn signal wire in the plug. You would need a 2-wire to 3-wire taillight converter to give you a separate brake light only wire.

If you're lazzy or you have to take half the dash apart to get to it then a 50w resistor is a good option. If you have no place for a resistor than just leave it as is.

@@Patrick94GSR It all depends on the lights on the vehicle in combination with the specific LEDs used, some may work, most won´t. Seems to be easier here in Germany (and most of Europe). So far no one, not even the big brands like Osram, offer replacement LED bulbs. You get some on Amazon, but here all automotive parts which are related to certain safety or environment relevant parts of the car have to have an ECE (European version) or KBA (German variant of the ECE) number stamped on or have to provide a written certificate of conformity. Otherwise you would void the vehicles operating permit (same as if you severely fail the biannual safety inspection "HU" commonly referred to as TÜV). And looking at that, there seem to be no LED replacements which have an ECE number. One manufacturer rather recently put some LED lights as replacement for either H4 or H7 bulbs in the Headlights into the market. But really only one brand so far and to this point they got certified only for a limited number of car models. They can not yet be used as a generic replacement (which I think as specific and standardized those headlight bulbs are, will only be a matter of time until they have been kind of crosschecked with a certain number of different models and headlight types.) So it is easier in the sense that here it clearly is just illegal to put LEDs in (at this point of time) and the vehicle would actually be shut down by the police and a complete inspection and repair would be mandated. Only after fixing the issue and getting it inspected the vehicle would regain an operating permit. Would it work that well to just replace them, I am convinced the big brands around here, Phillips, Osram, Bosch, Hella, would have got some products out already that fulfilled all ECE requirements and could legally be used as replacement. But as we don´t get any for years now, I think I go with what Alec said as there must be a reason that it just not happened. Despite this getting less and less relevant with newer cars having LED lights, at least in the back, nevertheless. For stock headlights LED has replaced halogen bulbs either in higher priced cars completely or can be ordered as an pricey option. At least they seem to have made Xenon lights obsolete in new cars. I bet this sounds harsh to some in the US, well at least in some states where there are no inspections or you might pass an inspection as long as you have some brakes and lights in a somewhat working condition. But we are glad to know that there is an almost 100 % chance of other vehicles around being roadworthy and they will not start disintegrating in front of me at 160 km/h on the Autobahn.

I recommend using the Error Free CAN BUS LED's that prevent hyperflash instead of using resistors for a few reasons: 1. Resistors can be a fire hazard since they get so hot and/or damage plastic components such as housings or bumpers (of course this all depends on the installation location). 2. There may not be enough room for resistors behind the housings. 3. Resistors create 2 additional wiring connections and an extra component that can all be points of failure. 4. As you mentioned, they may not be suitable for the electrical systems in newer cars.

Just a PSA for those of you with newer vehicles that utilize a body control module (BCM) - you may not want to use the ground wire in your light harness to ground the resistor. I had some interesting problems with that on my 07 Tahoe. Now I just use a self tapping screw and drill a dedicated ground point right behind the tail light. One lead of the resistor gets tapped into the signal wire, the other goes right to its own dedicated ground. I've never had an issue that way - there are a couple of videos on my channel about it.

A little constructive critique here.🤙 Hobby electric here that is a car mechanic. Not saying it is wrong but your 6ohm resistor should be swapped with a 12 or 14ohm instead to get closer to the combined power the halogen bulb pulls. Lets say your constant car voltage is 14v And your bulb is a 21watt one. And your LED light ACTUAL power draw is 6 watts (I've measured several ebay and expensive ones and they all are about 6 watts). To to mimic the original bulb you need to add 14 watts resistive load. And a 6 ohm resistor at 14v pulls 2.33 A (14/6=2.33) and that equals to 32.66 watts (2.33x14=32.66) that is overloading the cable by 188% when combining the LED bulb. You want 21-7 watts = 14 watts for resistor. 14V/14R=1A 1A*14V=14W But to be on the safe side if the LED is a weak one you can chose 12Ohm instead that pulls 16.3Watts and will be a lot cooler than your 33watt one 😁
@tullgutten

And this also works without any issue on new cars that have halogen bulbs since if you overlod them it will cut the power since it is seeing a short circuit if using 6ohm (varying from brands) but a 12 or 14 ohm is 99% safe. And the watt rating on the resistor only tells how much it handles before burning so always try to have the watt rating close to double that actual power draw on it. So a 14 ohm and watt one is perfect at 30 watt rating or higher (25watt rating works but it is getting hotter since it is smaller)

Hey Eric! Long time watcher, first time poster. The LEDs look great as does the whole truck! I may be a bit biased though. I have watched most of the series about "Dad's Truck" because I too have a GMT400 (1993) that was my dads. My truck has been an off and on project since 2010. It was wrecked in 2002 and was parked outside with no front sheet metal for years. My dad died in 2009 and it became a mission to me to get this truck going again so I could drive something that he loved. I would gladly accept the factory tail light housings if you decide to part ways with them. : )

Instead of using tape for the resistors that you could screw them in with some self tappers. I have found out that if you screw them in into a metal surface that it can help to dissipate the heat that the resistors produce. I had to do just that when I installed my turn signal LED's. Also there are LED flashers for some older vehicles that don't have a BCM.....just my 2 cents

Also, I used Meguiar's PlastX polish, not a sponsor, and it really cleaned up and brought the shine back to my OEM housings.

Resistors are like carburetors. It works but outdated. The best thing to do is use a relay designed for leds like another commenter said . Resistors get way too hot and need to be carefully placed in order not to burn plastics parts of the car. And yes,even in the few seconds of using a signal light they get up to 170+.

Exactly. There isn't any issue with the hitch wiring, that's just how the light is made, if you put one of those on you get a right and center turn signal because it's plugged into the dark green wire.

You can also change the flasher relay made for LEDs. This way you don't cut into the original harness Also uses less power(not that it really matters. But you wont need a resistor which gets hot after a long time of use. I replaced the blinkers with LEDs on my 2011 Impreza and just removed the original flasher relay and installed an electronic one This is also reversible as you just need to swap out the LED bulbs. The relay can also run the old bulbs, so no need to even swap it back.

I changed my tail lights and rear turn signals on my 2005 Silverado to LED bulbs but had to leave the running lights incandescent. The cruise control does not work if LED bulbs are installed.

Resistors are installed on brake/turn signals.

The third brake light comes on because it gets its signal from only one side of the brake lights, and because the brake flashers are integrated in the stop light (i.e. not using amber lights) it'll flash with the turn signal. Basically you need to run a wire from both brake lights with diodes in each side so you don't backfeed anything. Then it'll stay on solid with either turn signal, AND flash with the 4-ways on.

In the video where you installed the trailer lights, you only checked for expected signals - and mostly just one signal at a time. You wouldn't have caught any weird leakage currents with the testing you did. So it's still possible that the problem making the third brake light flash with the right indicator is due to a problem with the wiring, rather than a short in the unit.

For some applications they also make LED-compatible flasher modules that don't fast-flash when under LED loads. Not always an option, especially if one has no flasher module to begin with.
@MrFastFox666

A more elegant and easier solution is to use an LED compatible flasher to replace the stock one. Older vehicles like this one typically have it as a separate unit, almost like a relay. You don't need to touch any wiring, it takes load off the electrical system, and is super easy to revert to stock. Also with those resistors, if an led dies and you need to use an incandescent in a pinch, you'll overload the electrical system. This is not an issue with an led flasher.

I think you needed a large resister like that because you have it from the turn signal positive to ground, loading up the flasher - slowing it down. Thats why it slowed down with that hitch light flashing. If you measure the difference in tesistance between a std bulb and the led and put a resistor inline they should flash as before and cars like mercedes that use resistance to determine if a bulb is out should still work.

Eric, I'd be a little concerned about the heat that resistor is going to build of you're holding on the brakes for more than 15-20 continuous seconds at a traffic light or when in traffic. Best case scenario, the resistor just burns itself out. What usually happens though it's that the rest of the taillight wiring harness is resting against it and it melts into the harness, which as I'm sure you can assume has the possibly of rendering the brake lights inoperable, or even creating a short circuit. Your best option for installing these properly is too use the front turn signal circuit, since it'll be a separate circuit that is only going to flash with the turn signal and will never be solid lit up for an extended period of time like the brake light could be. Doesn't matter if it's on the front or rear when installing the resistor, the flasher relay is just looking for that load resistance for the left or right side, not front or rear. Or, just install a flasher relay that made for LED bulbs; direct install and no resistors needed with the LED bulbs.

@@ericthecarguy Yes. My daily 2004 Chevy Blazer. Uses two bulbs in each taillight, both function as running and turn/brake lights. Converted all exterior running and signal bulbs to LED and put the resistors just on the turn signal circuit in the front lamps, works perfect. Put a constant 12v to one of those resistors for more than 10-15 seconds and tell me you can keep your fingers on it. They're not designed for sustained power, just the momentary flashing of a turn signal circuit.

If you want to preserve the factory "bulb out" alert, check the resistance of an incandescent bulb that is the OEM-recommended bulb type. Then, check the resistance of the LED bulb setup (or just the bulb, if it's a bulb-only upgrade.) Subtract the resistance of the LED setup from the OEM resistance, and that'll give you the proper resistor ohm rating you need. Purchase the proper resistor and if an LED bulb stops working for some reason, your vehicle's "bulb out" alert system will still be able to function properly. That's my $0.02 worth.
