D-Lumina Under-Hood Light for Chevy Silverado & GMC Sierra — OEM Fit, IP67 Waterproof

If you work on your vehicle at night or need clearer visibility under the hood, this LED lamp upgrades the dim factory bulb to a durable, waterproof light built for longer life and stronger illumination. It's crafted as a plug-and-play replacement for the OEM part 12450086 and matches the original housing and connectors so you can swap it in without wiring changes.

Will this under-hood lamp fit my Chevy or GMC model?

The D-Lumina lamp is made to replace the factory under-hood light on a defined list of GM vehicles spanning late 1990s through mid-2010s. Check your vehicle year and model against the fitment list before ordering to ensure compatibility. It directly replaces OEM part number 12450086, eliminating guesswork if you have that part on your original light.

• Fitment includes: 1997 Buick Century/Regal; 1999–2002 Chevy Silverado & GMC Sierra 1500/2500, 2002 3500 models.
• Also fits 2000–2002 Chevy Tahoe and GMC Yukon, 2003–2014 Express and Savana 1500/2500/3500 vans.
• Direct OEM replacement for part #12450086 — compatible socket and housing design.

How much brighter is this LED compared to the original bulb?

Equipped with high-efficiency SMD LED chips, the D-Lumina lamp delivers substantially more output than stock incandescent lamps. You’ll notice clearer, whiter light that makes identifying components and reading labels easier during repairs. The LEDs also draw less current, reducing strain on the vehicle wiring while staying noticeably brighter.

• Uses 18 high-power SMD LEDs for intense, uniform illumination.
• Advertised as roughly six times brighter than the original factory bulb.
• Lower power consumption extends lamp life and reduces heat.

Is the light durable and weather-resistant for under-hood use?

This lamp is built for the harsh conditions found in engine compartments: heat, vibration, and occasional moisture. The housing uses impact-resistant ABS, and the lens is polycarbonate with a triple-layer coating for chemical and scratch resistance. An IP67 waterproof rating means it can withstand dust and temporary water immersion without failing.

• ABS plastic housing with PC lens and triple-layer protective coating.
• IP67 waterproof rating for dust-tight and water-resistant performance.
• Canbus-compatible design to avoid error codes on vehicles with diagnostic systems.

How easy is installation — will I need tools or modifications?

Installation is designed to be quick and tool-minimal: remove the original lamp housing, plug the D-Lumina unit into the factory socket, and secure it in place. The form factor matches the OEM part so no trimming or splicing is required. Most users can complete the swap in minutes with basic hand tools, if any.

• Plug-and-play replacement — connects to existing factory wiring harness.
• No trimming, soldering, or extra adapters required for supported models.
• Comes as a single under-hood lamp; check fitment for left/right or multiple lamp installations.

Who this is for: This under-hood LED is intended for owners and technicians who need brighter, longer-lasting illumination in the engine bay of compatible Chevy, GMC, and select Buick models. It suits DIY mechanics, fleet maintenance teams, and anyone replacing a failed or dim factory hood lamp who wants an easy, reliable upgrade without wiring changes.
