Help: on my GS4, the passenger DRL (daytime running light) goes out when the headlight comes on! The light works fine during the day, when the headlights are off.

So the bulb must work, but I imagine it must be an electrical relay issue.

Any ideas?

 

Thats how they work.

 

Actually, as DRL, they work fine during the day.

At night, when the headlights kick on, both DRL lights usually continue to operate (unless the high-beams are turned on & override the DRL).

Anyway, the passenger DRL is now off when the headlights are on. The driver-side DRL continues to operate as usual (remaining on when the headlights are on).

Anyone had this problem?

 

Theres actually 2 bulbs in your highbeam headlight housing. One 9005 for the high beams, and another small wedge "W5W" bulb that turns on with your parking lights.

Consider yourself lucky as the passenger is much easier to change then the drivers side due to space avaliable behind the housing.

Look closely, you will notice this other bulb, and just twist and pull from the back gently.

 

replaced the W5W bulb & everything is backed to normal!

Thanks for your help.
