Frequently Asked Questions About Morimoto Yukon XB Tail Lights
Does LF766 cover the longer Yukon XL?
The listed application includes Yukon XL from 2015–2020. Compare the original tail lights and connectors rather than relying on wheelbase or appearance alone.
Are the turn signals red or amber?
LF766 uses amber turn signals and red brake lights. That differs from Chevrolet LF767, which uses red turn-signal output.
Can LF766 replace the Tahoe or Suburban tail lights because they look similar?
Use the exact vehicle application. LF766 is the Yukon part, while Tahoe/Suburban use the separately listed LF767 assemblies and wiring. Similar styling does not establish interchangeability.
Is reverse illumination included without the Boost Bar?
Yes. White LED reverse lights are built into the pair. Morimoto’s Backup Light Boost Bar is an optional, separate accessory.
What comes with the base LF766 pair?
Two complete tail-light assemblies and the listed adapter harness. Optional accessories such as the Boost Bar are not part of the base pair.
What should I verify on a Canadian Yukon?
Match the original lamp connections and mounting, then test brake, turns, parking and reverse. Morimoto states US-spec testing; confirm the actual Canadian equipment.
