Hello FJ and forum friends! So thankful for this site and community. I'm hoping someone out there can help me resolve a backup light issue I'm having. Hi, I have a 2007 FJ. I'm currently experience a low-voltage drop with my reverse lights. A few years ago I replaced the OEM backup bulbs with some Diode Dynamic bulbs. After some initial low output glitches the lights have worked perfectly. About 6 months ago the lights begin to intermittently stop working and then eventually stopped all together. I thought the bulbs might be the issue and had Diode Dynamics swap out the bulbs under warranty. That did not resolve the issue. Graciously, they then sent me their latest model that has built in resistors and unfortunately I'm still experiencing the same issue. A few years back I tapped the reverse light (yellow/red wire) underneath the drivers side door panel for a backup camera. I thought maybe that was the issue and removed the tap and camera. The lights still did not work. When I checked the cable at the TAP POINT the voltage reading was very low at around 8V. I replaced the rear backup light with the original OEM bulb, heard an audible BEEP, and then the voltage when back up to 12V. The LEDs and the OEM bulb lit up. I put the LED back in and everything seemed fine. However, eventually the voltage reading drops back down and the lights go dim or off. I have repeated this process a number of times. I do have a number of auxiliary lights (driving lights, backup lights, LED trim lights on the interior) wired up but nothing excessive. I also just had the electrical system checked out and alternator and battery are OK. I had them replace a bad Positive terminal cable and they said the vehicle's ground checked out OK. So, I'm at a bit of a loss here and hoping someone might have some insight to help me investigate where or how this might be happening. I'm going to replace the battery anyways, but I'm sure that is not it. Everything else with the electrical components are all operating normally. Thank you all in advance.
