LED Turn Signal Mirrors?

Question

I bought the aftermarket turn-signal mirrors for my car. When i hooked them up right to my turnsignal light's wires, it doesnt work, but if i hook it up to those same wires using a relay (still getting the power from the lights) they work fine... can someone explain this to me and are there any other ways i can do this? PS. Worked on car electronics for 10+ years...

Answer 1

it seems as though when you connect the lights directly, the resistance is too high so the thermal flasher will not get hot enough to flash.  do they light up, but not flash when connected directly or do they not light up at all?  i'm guessing they light up, but just don't flash.  i suggest just using the relay if you find a decent place to hide it.  hope this helps.
