Wasn't sure where to post this cause its not Audio, but it does have to do with towing since that's what I do with the Burb. I've installed four LED amber turn signal bulbs and have found that with the stock flasher they flash real fast. I got a Grote LED flasher from NAPA and the turn signals don't work at all. What do I use? LED flashers are all over the internet so how do you know what works?
