Hi - I'm trying to install backup camera - it needs 12v - can I hook the power up with reverse tail light - I suspect it is 6v only? I want to poser the camera when reversing the car. Thanks
Your camera is 12V. You suspect the reverse tail light is 6V. If your vehicle is 12V, as most are, then the reverse light is 12V. Some vehicles, large trucks, etc., may be 24V, but 6 V vehicles haven't been around for many decades. Confirm that your camera voltage matches the vehicle voltage.
Related to your question- There may be times other than when you are in reverse that you want to have the camera on. For example, if you are installing it on a motor home. I've driven a MH with the camera on most of the time and it has been useful as it provides a better view immediately behind the vehicle than the side view mirrors. If we don't want it we can turn off the monitor.
If you don't have a live 12V feed at the back of your vehicle, you could either run the wire from the front from a terminal which is switched on when the key is "on", or consider connecting it to a tail light wire. You'd have to turn on the tail lights to have the camera activate, but you can do that any time and leave them on while driving. At night the camera would always be on, but the monitor can be switched off. Bear in mind that some cameras can take several seconds (especially when cold outside) to provide a decent picture, so if you connect it to the reverse light you may need to be patient before backing.
