I installed new led back up lights and now the backup sensor does not work properly. It beeps when it shouldn't. The back up camera works fine. Any thoughts? It a ford f150 2008

Question type: Car Customization
Ford f150 2008 10 amp fuse. Is it not enough for the new lights? Would there be a problem putting in a 15 amp fuse. The new lights work but causes that issue. If I leave one of the old lights, original factory, and one new one, everything works just fine.
Thanks for any suggestions.

Led's draw far less current than the regular bulbs. The lights must be wired into the same circuit as the sensor. The part store sells load equalizers normally intended for led blinkers but they should help your situation

Thanks Andrew, if LEDs run less shouldn't the new bulbs just work fine then. I didn't have the problem before. Also where would a load equalizer go and are they hard to install? Thanks
They are wired inline with the wiring for the reverse lights. Led's to weird things to circuits. I am not going to pretend to understand how the backup sensors work. But my bet is they are in the same circuit as the lights. If they are in series then that means the sensors get less voltage maybe? I also don't have the wiring in front of me either.

Yes they are all connected, the lights, sensors and backup camera. I took the fuse out to try. It really strange that these lights do that. If I can I'll add a picture to show the lights. Also weired that works with one old and new light. Too much power needed I guess for the new lights.

Here is a picture of the old and new lights and the company the new one came from.

Hey Andrew, thanks for your help so far. Any ideas if I put a 15 amp in the 10 amp slot like the guy at the store suggested. I've read it could cause a fire or wires to heat up, but the reverse is not on very long so I think it shouldn't heat up too much.
The fuse size won't make a difference. It just means it will blow sooner. The system won't work with the led lights unless there is more load on the circuit. Led lights put next to no load on the circuit. The sensors for some reason need that load there to function properly. Switch to normal bulbs or wire in the load equalizers.

Thanks for your time and responses. I guess I'll go back to the original lights.
There is a possibility the sensor is looking for a certain draw when the system is activated. If the draw is low the sensor may send fault signal thus causing the problem. Disconnect the LED system leaving it in the factory condition. If the problem corrects itself there is a good chance the sensor is detecting the lower reading causing a fault.

thank you, I have tried leaving just the original lights in there and everything is fine and also fine with one new one and one old light. So there seems to be the problem only when both new lights are in.
