Why am I Not Getting Power to My Trailer Lights?

Firstly, make sure that the wiring from your trailer to your vehicle is in good condition and properly connected. If everything looks alright here, then it’s likely that the issue lies with either a blown fuse or bad bulb.

To check if it’s a blown fuse, open up your vehicle’s fuse box and see if any of the fuses have been burnt out. Replacing these should solve the problem right away. On the other hand, if all of the fuses look good then its time to test out each individual light on your trailer by removing them one-by-one and checking for signs of life using an LED tester or multimeter device.

If you find that no matter what you do none of them turn on then its very likely that they will need replacing as this usually means their bulbs have gone bad over time due to wear & tear. Once replaced however you should be back up & running again with no more issues!
