Frequently Asked Questions About Peterbilt 388 Cab Lights

Will these cab lights fit my specific year Peterbilt 388?

Most aftermarket cab lights for the Peterbilt 388 are designed to fit model years 2006-2015. However, some variations exist between early and late production models. Pre-2008 models may require different mounting brackets due to slight roof curvature changes. Always verify the specific year range listed for each product, and when in doubt, measure your existing light spacing or contact us with your VIN for confirmation.

What's the difference between LED and incandescent cab lights, and which should I choose?

LED cab lights draw significantly less power (typically 80% less), last 50,000+ hours compared to 2,000 hours for incandescent, and produce brighter, more consistent light. They also generate less heat, reducing lens discoloration. Incandescent lights are less expensive upfront but require more frequent bulb replacements. For trucks driven regularly or in commercial applications, LED lights typically pay for themselves within 12-18 months through reduced maintenance and fuel savings from lower electrical load.

How difficult is the installation process, and what tools do I need?

Installation typically takes 2-4 hours depending on experience level. You'll need a drill with metal bits, wire strippers, crimping tools, silicone sealant, and basic hand tools. The main challenges include drilling through the cab roof (measure twice!), properly sealing to prevent leaks, and routing wiring to avoid interference with headliner. Many drivers recommend using butyl tape in addition to silicone for waterproofing. If replacing existing lights, the job is much simpler as mounting holes are already present.

Are these cab lights DOT approved and legal in all states?

Quality aftermarket cab lights should carry DOT approval markings (look for "DOT" stamped on the lens). Federal regulations require amber front and side-facing markers, with red for rear-facing positions. Some states have additional requirements regarding light intensity and positioning. California, for instance, has stricter standards for aftermarket lighting. Always verify that the lights you're purchasing meet FMVSS 108 standards and check your state's specific commercial vehicle lighting requirements.

What styles and finishes are available, and how do they hold up over time?

Common styles include the classic teardrop (watermelon), rectangular, and modern LED light bars. Finishes range from chrome plastic, die-cast chrome, polished stainless steel, to powder-coated aluminum. Chrome plastic is economical but may peel or fade within 2-3 years. Die-cast chrome and stainless steel options cost more but maintain their appearance much longer, especially in harsh weather conditions. Smoked or clear lenses are available, with clear being required for commercial DOT compliance. Consider your climate and washing frequency when choosing finishes.
