Default Led headlights

I bought some led headlight for my 86 samurai I hooked they up and they want come on. I can go straight to battery and they work , I'm guessing it's something to do with ground maybe anyone have a solution or run into this problem

Most Suzukis, Samurais included, use a ground switched headlight circuit - you'll need to get a relay harness built to work around that - ask your LED headlight supplier if they can provide one.

I had the same problem. One wire is live the other 2 are grounded 1 for low and one is grounded for high beam.but never grounded at the same time. I used 2 relays 1for high one for low. Use the Sami light wire for ground for relay. I found wire diagram on line.

heres a generic wiring diagram showing how "earth driven" lights work and how to fit additional lights such as driving lights. just follow the wiring from the headlight switch and it will make sense. Adapt this to work in your situation.

Will this work on a newer one with DRL? I really don't want to cut wire. Might use DRL to power some led running lights like modern cars???

principle is the same, our cars here don't have the DRL option so i fitted aftermarket ones, all I did was wired them direct from the main ignition relay so they come on and off with the key, and a relay wired in the circuit so when the headlights come on the relay energises and the DRL's turn off as required by the regulations here
