Question:

I have replace the Stop/Tail light bulb with a LED on my 2011 Mazda CX-7 to try to fix a melting tail light lens issue. Now on occasions my Stop/Tail light flickers on one of the elements in the LED Bulbs. This happens on both sides. I know using a Load Resistor will fix it if its on the Turn signal bulb. Do you know what the fix or issue is for this? I believe it was a 7443 bulb I replace with an LED.

Expert Reply:

Both the stop and tail light bulbs used on your 2011 Mazda CX-7 are the 7443 type as you noted.
We offer this bulb type in both halogen versions like # P217443B (possibly what you had originally) and in LED types like the Putco # P237443R360.

LEDs are very high efficiency lights that can sometimes light up from even the low-level residual current in vehicle or trailer wiring.

Load resistors that will correct the flicker. Use one per bulb. We offer # DI34ZR.
