I have a 03 kw t600 n high beam lights workin fine but only one low beam headlight workin I changed light but still not workin

SOURCE: high beams wont turn on.

First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

had the same problem on my 92....check under the hood on the drivers side,towards the front,there is a "junction box" with all of the lighting wires connecting from the switches to the lights.My wires were all corroded inside,so I cleaned the ends and bought a new box from the local electronic supply store.The problem has not come back.

Cheers

hi from uk provided you have checked bulbs are ok? then this fault may be the relay for the low /dipped beam has gone faulty if you check h/book you may find location of low beam relay there is relay for high and one for low beams if you find both relays ? try switching? this will confirm relay fault if you then have low beam but no high ? b4 you buy new relay other than tis the other possible fault may be the actual di/high beam stick control ?

high low switch is gone or both low beams bad
