Cool New headlights not working

Ordered a set of new led headlights from eBay but I can't get them to work properly, I ran a hot wire from the extra red wire to the + on the battery still nothing. I was told to do this by a local shade tree mechanic I don't know much about wiring.

As always all advice is greatly appreciated! Thanks in advance.

Re: New headlights not working

LEDs are polarity specific...ground has to be ground, and hot has to be hot...cant tell much from your pic.

Re: New headlights not working

Even if the old incandescent bulbs worked fine, if you are reusing the original headlight plugs, possible that corrosion is preventing a good connection. It doesn't take much size difference to cause problems between old sockets and new inserts.

Re: New headlights not working

You may need relays to get the bulbs to have sufficent voltage.

Re: New headlights not working

You'll probably need to repin your connector. LEDs often are wired to H4 pattern, just gotta swap two wires around in the connector.

I just wanted a nice set of headlights, I don't think $109 is all that cheap for headlights. Not sure what you paid for your set but I'm sort of on a budget. Thanks.

Re: New headlights not working

I wouldn't say its always cheap lights either, lazy/minimizing minor stock changes for what is essentially an unnecessary part number since h4 & 45xx use the same connector, on the lazy side, they should be throwing in a sheet with the above that says if you are using them in a 45xx system repinning will be necessary (h4 being by far the most common, especially from an asian/euro perspective).
