FJ62 LED Headlight Problem (1 Viewer)

[shane738]

Hello All!

Just three weeks ago I bought my first 60 series and also my first 4WD. Along with my purchase, the previous owner bought LED lights that he never installed and gave them to me since he no longer needed them. I have finally got to installing them and have run into a couple of issues. At first, the pins were not wired correctly and kept blowing fuses which I have now fixed and had the lights working but when I hit my high beams they come on but they turn off my normal driving lights. Also by this happening it has made my spotlights not work because the high beams are not properly working only having the high beams on and not all four lights. If anyone can help me with my issues I would be really appreciative as its a tad annoying ahahah

A picture of the front of the vehicle would help. We are talking about a 60 here....with round headlights right? And a pair of aftermarket driving lights mounted to the bumper? If LED headlights and a 60 did you find some lights designed specifically for the fj60 or did they come with a conversion harness?

As for the additional lights. If they are wired legally they will either only work with the low beams (fog lights). Or only work with the highs (driving) lights.

Rectangle lights. The aftermarket lights are wired fine they worked before I put the headlights on it runs off the high beam but when I put the LED lights in when I hit the high beam only the High Beam lights (the ones second from the outside) turn off but then the headlights turn off (the ones on the outside) when all four should be running when I hit the high beam. They didn't come with a conversion harness they only had the H4 harness to adapt. But as soon as I put the old lights back in the lights all work perfectly fine.

Ok. So it’s a 62 not a 60.

Remember that these trucks headlights are wired backwards to how most other vehicles are wired. So most vehicles these days have a ground connection all the time and the switch sends power to the light of choice. On 60/62 the lights have a common power and the headlight switch is sending power to one circuit or the other. Because of this most LED light conversions act strange. You need to buy or make a conversion harness to allow the lights to work properly.

Your stock halogen lights work fine because they are filament bulbs and have no care in the world for the direction that current is flowing. LEDs however only allow current to flow in one direction.

Ah ok that makes sense. Is there any available harnesses to buy and would one like this work?H4 LED Headlight Canbus Conversion Kit Decoder Canceller Load Resistor HID Xenon 980065740861 | eBay

lots of good info in this thread:

LED Headlights for FJ60 and FJ62 Landcruisers

I've been getting this question more frequently as the cost of LED headlights has come down out of the stratosphere. They are now just a little more expensive than the best Halogen headlights, and so there is a lot more interest in them. Before you whip out your credit card, there are a couple...
