I've experienced a strange problem on my first gen LS. The lights work fine, but whenever the highbeams are used, only the right side bulbs remains lit with the highbeam and both fog lights along with the left side bulbs completely shut off. When the light switch is back to normal headlight, all the lights turn on. would a faulty bulb do this ? I would like to get an opinion before i start to take off the headlight assembly to change the bulbs.
thnx.

 

anyone?

 

I'm not exactly sure how the headlight assy from the 1st-gen LS is constructed, but by default, fog lights automatically shut off whenever high beams are turned on. DOT law states that a maximum of 4 lights on the front of a car can be turned on at the same time.

 

lexusk8 is correct, the fogs automatically shut off when the high beams are on. All you need to do is replace the bulb in the left headlight, sounds like one of the filaments (for high beam) is out.

 

hello, seems like a burnt out bulbs, and if you replace it, try silverstars by sylvannia theyre close to hid,
