05 gmc signal light questions.

[Justin1022]

hey i think i have a problem with my 2005 gmc duramax headlights when my headlights come on my signals are lit up same with that little bulb beside it on each corner. (not sure if its normal for them to light up) then when i signal left or right that little bulb flashes with whatever signal light is on. (not sure if this is normal) seems odd i have a 03 and it doesn't do that but thought maybe 05 they changed them up a bit? thanks in advance

and sorry if this is in wrong spot seen the electrical spot but it seemed more for stereos.

Sounds normal to me. The front little 194 side marker bulbs should be illuminated along with the front main running lights, then flash alternately with the front main signals with the running lights illuminated. Sounds like your 03 is the one with a problem.

Hm well that's good to no I wish there was a easy way to post a video then it would be alor easier for you guys to see but sounds normal so when your head lights are on your signals should be illuminated also?

The front signals are dual intensity bulbs. They should be illuminated at low intensity along with the outside markers when the headlamps are on.

Yup that's what it's doingg sounds like my poor 03 has to come apart now lol. Thanks for the help much appreciated!!!

No problem glad to help! more than likely you just need some 3157 signal bulbs, but when you change them out pay close attention to the bulb socket. They like to burn out and cause poor connections.
