Review on Enhance Road Safety with Syneticusa 7443 Red LED 🚦 Stop Brake Flash Strobe Rear Alert Safety Warning 12-LED Light Bulbs by Fred Griffin

Must give 1 star because while functionally it does what it promises in terms of flash and installation as a direct replacement, it caused some glitches on cars without keys starting and lock unlock. Whenever the light was on, the key didn't show up. Turn off the light and it works again. This happened even if you left the light switch on after turning off the car and the light automatically turned off. When you came back, the remote control didn't open the car automatically. These return. For reference, this was a 2013 Highlander with a keyless system. It may not affect other models or even years in this way but be aware that I have seen other reviews with electronic failures or failures due to these bulbs and I now believe they are true. Unfortunately, I'm going back to incandescent bulbs.
