I got my LED bulbs in today. They seem pretty bright outside of the housing. They will be installed up front because I am going with the sequential lights for the rear. My questions is do I need to get a flasher because the turn signal isnt working. It blinks but is not like on and off. I assume that if its not blinking in the rear then its not going to blink in the front either. If I need a flasher where do I put it and does any modifications need to be made to anything?
