Product Description

This GMC tail light exchange services is a rebuilt replacement for your 2015 - 2020 GMC Yukon, Yukon XL, Yukon Denali, or Yukon XL Denali with a factory tail light/brake light that is no longer working or is functioning intermittently. Our rebuild corrects the root cause of the failure that prevents the tail and brake lights from illuminating. Because our rebuild is more robust and more flexible than the factory build, our exchange lights end up better than new.

Our rebuilt tail lights are used tail lights with repaired internal circuitry. The only way to access the failed circuits is to cut through the back side plastic, which we do with a laser. The hole is then covered with our custom cap to form a waterproof seal. To see more about our result, see our blogpost here. These tail lights are cleaned and polished, but do have light scuffs and scratches typical of normal wear. 

The benefits of the GMC tail light exchange service are:

  • No Vehicle down time
  • Your tail light ships the day you order (before 3pm EST)
  • Backed by our 1-year guarantee


  • If Circuit Board Medics does not receive your core within 15 calendar days of the ship date of your exchange unit, an additional core charge of $150 will be charged to your credit card for each tail light that was ordered.
  • Your original tail light must meet the following qualifications in order to avoid a $150 charge:
    • It must be an original (OEM) GMC tail light (No aftermarket substitutions)
    • No prior repair attempts
    • No fire or water damage
    • No cracks in the housing or parts broken off
