An H13 to H4 headlight adaptor from RIGID.

A small part that solves a specific and annoying problem: your vehicle has an H13 headlight connector and the light you want to fit is an H4. Rather than cutting and splicing the vehicle's factory loom, this plugs between the two.

Keeping the original wiring intact matters if the vehicle is ever going back to standard, and it removes the joins that corrode and cause flicker years later.

Check which connector your vehicle actually has before ordering — send us the year and model if you are unsure.
