Hot Rods When installing LED Lights (caution) ruined a brand new light

Just wasted a bit of money due to a mistake. This caution was even mentioned in the directions that come with LED tail lights but who reads directions ?? I bench tested them before actually installing them in the Model A with a 12 volt battery & jumper wires on the workbench . Well there are 3 different color wires that come out of each light. Well I crossed the wrong wires and damaged the light for good / unreturnable... Be careful even on what seems to be a very easy job... Gene

 

Ya, we don't need no stinking instructions!
Been caught more than once not reading (ya think I would learn) and get to spend money a second time!

 

Most LED's just wont work if wired backwards. But I've seen numerous that didn't come with instructions to indicate which wire is which? So I also test them first to check what's ground, and which wires are for brake and running lights.
I've been lucky so far that no issues burning any out.

 

Instructions are for sissies!

 

I never had that problem with an incandescent light bulb. I guess I'll just stick to them.

 

just the Nostalgia gods reminding you that speaking of LED on a traditional site is just wrong

 

That’s not a mistake, that’s a prototype

 

Curious what the three wires are for? I can see hot and ground, but the third?

 

Two hot wires for the tail lights. Running lights and brake lights.

They say you learn from your mistakes. I should have been a genius by now.

 

So the tail light and brake light is in the same unit I suppose? I just assumed a separate unit. Must be a high tech 1157?
