So I bought a cheap HID kit and they need the relay kit.. I know I can make one myself so I'm NOT paying $20 for one on ebay. What kind of resistors do I need? I saw a DIY for a w210 but now I can't find it..
HID + relays = bulb out warnings and flickering. Sorry, the SAM needs to see a load. Use the digital kits others on here have had success with (STF), they aren't that much more expensive. Several folks here have had good luck with kits that were less than $100. Or just buy some good +50 bulbs, get almost as much light and don't screw around with wiring.
