Hello all and good morning,

07 HHR my right turn signal started blinking fast, checked bulbs and the back right was burnt out, Old bulb was Wagner 3057KX I picked up some Sylvania 305K ST, They work fine at first but half way to work 20 min. the right starts blinking fast again, on right turns. I get to work wait a little bit go out and it works again. Seems like it has an issue when it warms up. It is only the right one. Am I missing something. It's just a light bulb???

 

Could be a bad bulb, more likely corrosion or loose ground or the bulb didn't get twisted right.

 

 

Isn't the first time something made went bad.

 

Changed out the socket.. switched out bulb I used a 3057 K ST that replaced the 3057KX. Going to try and find the 3057KX and see if that is it.

 

The letter suffix has little to do with the operation of the bulb, just life expectancy.

Did you check the ground? Or the connection on the signal stalk?

 

x2 what don said.
