How difficult is this on a scale of 1-10? I can do basic wiring but that's about it.

The stock switch doesn't have that much power going through it anymore. Mine would get really hot prior to the relay mod, now it does not. By adding the relays there's really no major draw through the switch resulting in an overheat.

Can you crimp/solder? If so, it's about a 2 (if 1 is the easiest and 10 the most challenging). All the work is under the hood so there's no monkeying about under the dash playing with wires.

You missed my point completely. Maybe the next guy wishing to do this mod won't.

Or you could just say what your point is instead of expecting people to pick up on it.


Unless I am wrong in understanding your POV, you are saying that if the stock switch reaches its failure point, there is a fail safe built in that ensures the lights come back on, or atleast flicker until you can get off the road. If the relay, or an aftermarket switch fails, there is no fail safe and you are SOL driving blind. Same thing happens if you run a fuse on the circuit instead of an auto reset breaker.

Let me try to understand your non-clearly stated point:

-The stock switch has a thermal management system in it that protects the system from too much current fly by flicking the lights off and then subsequently back on a moment later, allowing you time to get off to the side of the road.
-You are saying that without this system to protect the Jeep, if something happens with your wiring, then your headlights go out completely.

You realize most modern cars do not employ such a feature, correct? Your point is now null and voided, if you did your wiring correctly then you should have ZERO issues with current over-draw. That means using the appropriate relays, wiring, and fuses, and not running them around or near any substantial heat sources.

I highly HIGHLY recommend this modification to ANY Jeeper. Modern cars don't employ this ancient technology anymore, they all rely on relays and fuses.

Maybe I'm just retarded. But I'm STILL missing the point... The stock switch has a thermal shutdown, yes. But how would that fact make someone not want to do this conversion

If anything, that's a reason why one WOULD do this... it puts less strain on the stock system making it LESS likely to trigger thermal shutdown and potentially extend the life of the switch.

Most, If not all modern cars do have such a feature. ether through the switch , a circuit breaker or other electronic control device. That said, I add relays on all my headlamps. I use circuit breakers on the supply side of the relay. But yea no short no problem.

Will these work even though they are 5 pin relays. I'm going to use them for the relay headlight upgrade.

Those should work fine... Actually I might buy a couple of those sets...

Yes those will work fine. You will not use pin 87a. Use a terminal pick to remove the 87a lead from the socket.

I did this mod on my 01 TJ. I only had a 2 volt drop at the bulb. But, 2 volts makes a big difference. One of the best mods i've done. Highly recommended.

I did that mod quite a few years ago on my XJ for the same reason. Major improvement with standard halogen bulbs. I also do the same for my trailer wiring and add a switch on the ground side of the relays to de-energize them (no power to the trailer connector) when I am not towing.

From what I've heard, the downfall to LEDs are related to heat (or lack of). They run at much less amp draws as well as less heat, keeping them cool to the touch. This is great for southern jeepers, but for those of us up north that experience snow and sleet, we need a bulb that provides heat to the lense to keep the snow from building up and freezing.

I know some LED headlight manufactures are in the process of designing a heated lense system to provide just enough heat to keep the lense clear from snow and ice build up, but I can imagine this will only increase their already high price of their light kits.

Anyway, props to the OP for doing this write-up, very well done.

Actually, LED lamps are notorious for producing a LOT of heat, that's why every manufacturer of high intensity LED lamps has designed a heat sink into the back of the lamp. I'm sure the TruckLites produce plenty of heat themselves. You should feel some of the LED light bars me and some buddies use after a few hours of making our own daylight..

JeeperDon. The switch is the weak point in the lights for sure. The advantage to the relays is that you are minimizing the current flowing through the switch. Usually when the switch fails it fails open and you are left with no lights at all. You can still use a circuit breaker to feed the lights. Yes, the feds require lights to fail at low beam for any system failure on all new cars. The YJ predates the requirement but I am unsure exactly when it was put into effect. It was definitely an OBDII change so sometime after 96.
