Will these cab lights fit my specific year Peterbilt 379?
Most aftermarket cab lights are designed to fit Peterbilt 379 models from 1987 to 2007. However, pre-1987 extended hood models may require different mounting brackets due to slight roof variations. Always verify the product description matches your truck's year and hood configuration. If you have a flat top sleeper, standard 5-light kits work universally, but raised roof models may need custom mounting solutions.
What's the difference between LED and incandescent cab lights, and which should I choose?
LED cab lights draw significantly less power (typically 0.5 amps vs 2-3 amps for incandescent), last 50,000+ hours compared to 2,000 hours, and produce brighter, more consistent light. While LEDs cost more upfront, they eliminate frequent bulb replacements and reduce electrical strain on your system. Incandescent lights offer a traditional warm glow some drivers prefer and are easier to find replacement bulbs for on the road. Consider LEDs if you want long-term reliability and modern brightness.
Can I install cab lights myself, or do I need professional installation?
Installation typically requires drilling five holes in your cab roof, running wiring to your clearance light circuit, and properly sealing all penetrations. You'll need a drill with metal bits, wire strippers, electrical connectors, and quality sealant. The job takes 2-4 hours for someone with basic electrical experience. Critical steps include using a template for proper spacing, applying adequate sealant to prevent leaks, and ensuring proper grounding. If you're uncomfortable drilling into your cab or working with 12V wiring, professional installation runs $150-300.
What styles and finishes are available, and how do I match my truck?
Cab lights come in several lens styles including classic amber, clear, smoked, and red. Housing finishes include chrome (most popular for show trucks), black powder coat (for murdered-out builds), and stainless steel (best corrosion resistance). Traditional teardrop-shaped lenses offer the classic Peterbilt look, while rectangular designs provide a more modern appearance. Match your existing chrome accessories for consistency, or choose black housings if you have black mirrors and bumpers.
How do I prevent water leaks after installing cab lights?
Proper sealing is crucial to prevent costly cab leaks. Use a high-quality butyl tape or silicone sealant rated for automotive use around each light base before mounting. Apply sealant to screw holes and use stainless steel screws with rubber washers. Many drivers recommend adding a thin bead of clear silicone around the entire base after installation as extra insurance. Check and refresh sealant annually, especially if you notice any water stains on your headliner. Quality light kits include gaskets, but adding extra sealant provides peace of mind.
