Check the ground especially if it start blinking all the marker lights with the turn signal. Bad grounds do cause the lights to ground through the others causing them to be real dim and all to blink.

the rest of my light just work fine, i find it weird thou, here is a pic of it, my turn signal works just fine. it was out before i installed the lights. so it cant be the new lights. the only thing i can think of it being is the socket, i will replace it tomorrow. so anymore help will be thanked, sry for the horrible pic, i was just trying not to get rained on lol

Good old Bill

Check ground for that t-sig bulb. Looks like its back feeding.
