I used gm sockets from auto zone and retrofitted them to the park light housing. I heated and open up the park light. And dremeled out the hole for the gm socket and designed it to click in. So I used 1157 ( I think) bulbs. For my park light and it would flash the high side for signal. I have some pics in my photo gallery.
Wiring I tapped the power wire from the stock signal and ran it up to the gm socket the had 3 wired and tap the positive and ground from my park light to it.
Ran it for a long time with no problems.
