I just ordered and installed new 4300 headlight bulbs for my 06GS300. The problem is when I turn the headlights on its only on for 5 seconds before both go off one after the other.

Does anyone know what I should do?

 

Sounds like it could be the ballast, what brand bulbs are they.

That's certainly sounds like a ballast issue but it's pretty rare to have both ballasts go out at the same time. If it was a fuse issue they wouldn't turn on at all.

You are going to use elimination logic here to find out what the issue is.

Did both your previous lights go out at the same time?

Are the lights dim when they work for the first 5 seconds?

 

d2r?!?? 3gs uses d4s bulbs

 

exactly! hope you can get an exchange.

 

check your wattage on your bulbs, my uncle purchased i believe 65w bulbs instead of the 35w bulbs that our cars take

 

Ur using the wrong bulb

 

What they said ^

 

Thanks guys, just ordered the correct bulbs. I hope this works.

 

Did u check wattage ratings also? Just in case? lol....

 

Have anyone replied, same problem here

 

Sounds like a compatibility issue where the new bulbs draw too much power and shut down to protect themselves. The size is D4S but they also need to be 35W 12V. If the bulbs match those specs and still aren't working, they probably arrived defective.
