I installed one of those wiring converters from Erik's that makes the front marker lights come on with the headlights. When I switched to "service drive" it worked just as it should in the parking lot. The headlights and park/marker lights were both on. I decided to run a few errands, so I fired my Deuce up and headed out. I parked at the local mall and found that both headlights had burned out after five minutes of driving. You really can't install the conversion piece wrong. There's a slot that fits a tab at both ends so you end up with the right wiring orientation. I would appreciate any advice my fellow SS members may have.
