Piston Slap: Traversing the World of LED Retrofit Bulbs!

Sajeev,

Your recent Piston Slap on HID lights reminded me of a problem I had with replacing tail lights on my wife’s 2009 Traverse. One of the OEM bulbs burned out, so I decided to replace both brake/tail lights with LEDs.

The LED lights worked great and were brighter than the OEM bulbs, but there was just one problem–the turn signals would blink rapidly, just like they did with the burned out bulb. After I went back and RTFM I learned the rapid blinking or “hyper-flashing” occurs when a bulb is burned out OR the system is drawing little to no current. Since the LEDs use a lot less power, the system thinks the bulb is burned out.

  • Slavuta I don't know how they calc this. My newest cars are 2017 and 2019, 40 and 45K. Both needed tires at 30K+, OEM tires are now don't last too long. This is $1000 in average (may be less). Brakes DYI, filters, oil, wipers. I would say, under $1500 under 45K miles. But with the new tires that will last 60K, new brakes, this sum could be less in the next 40K miles.
