Hi,
I bought a rear work light for my truck. I already had a wiring connector at the back. I just bought the original lamp, connected it, and unfortunately, it doesn't work. It doesn't work when I turn on the headlights, and I also checked with reverse gear engaged. I started the engine. Nothing happens. The lamp doesn't light up. I checked with a multimeter, and there's no voltage at the connector. Should this lamp have an additional switch? I have all the relays and fuses in the fuse box; nothing is missing. Please help. What else can I check? I've marked the lamp I'm having trouble with in the photo.
