I put a flat deck on my pickup. I ordered Grote lights, made nice little boxes to put them in, but I didn't realize that the lights I ordered used one bulb for both turning and breaking, while the original truck lights had independent bulbs. So, after some googling I learned that you can get a converter for adapting trailer lights to the 2 wire system from a vehicle with the 3 wire system. One trip to Wal-Mart, converter in hand, problem solved I thought. Except it doesn't work. Go to the converter manufacturers website (Hoppy's) and it says the converter won't work for what I want it to do. I can't think of why, how does the converter know if I'm hooked up to a trailer or not. Anyways, what I'm looking for is some way to make this work, either with the converter I bought or some other way. I don't really want to make new boxes and order more lights. Anyones help would be much appreciated. Thanks.
