About this part

LK-15841610-1123

Both headlight harnesses for the GMT900 Sierra. The connectors on these crack and let water into the pins, which is why one headlight starts working intermittently before it stops altogether.

What matters when you install it

  • Left and right pair✓
  • Sealed connectors✓

Before you order

Is this the same part as the OE number?

It is an aftermarket part engineered to the specification for 15841610. It is not a genuine OE part and we are not affiliated with the manufacturer. The cross-reference tells you what it replaces.

How do I confirm it fits my vehicle?

Match the cross-reference numbers on this page against the number on the part you are removing, or send us your VIN / engine model and we will confirm before dispatch.

What does the warranty cover?

24 months against manufacturing defect — material, workmanship and function. Wear items and damage from incorrect installation are excluded. Claims go to a US address, not overseas.
