RIGID Industries H13 to H4 Headlight Adapter

Running a Truck-Lite headlight kit from RIGID Industries and hitting a plug mismatch? This H13 to H4 adapter is the part that solves it. It bridges an H13 harness connector to an H4 headlight plug — one adapter, clean connection, no splicing or custom pigtail fabrication required.

The conversion is straightforward: your existing H13 harness connects to one end, your H4 headlight plugs into the other. RIGID engineered this specifically for their Truck-Lite headlight kits, so the pin configuration and wire gauge match the hardware you're already working with — not a pulled-from-the-bin generic adapter.

We stock this because connector incompatibility is one of the most common friction points in an aftermarket lighting swap. The spec that matters here is simple: H13 input, H4 output. This adapter does exactly that. If you're mid-install and the harness and headlight aren't speaking the same language, this is the fix — and at 1 adapter per pack (RIGID part 55007), it's worth grabbing before you're deep into the job with nowhere clean to terminate the connection.

Professional installation is recommended. Pairs with RIGID add-on components including part numbers 1063, 1067, 1031, 30130, 30140, and 30150 for a complete lighting build.
