Peterbilt 352 Lights

Frequently Asked Questions About Peterbilt 352 Lights

Will these lights fit my specific year Peterbilt 352, and are there any model variations I should know about?

Most aftermarket lights for the Peterbilt 352 are designed to fit models from 1969 through 1981. However, there were minor grille and mounting point changes between early models (1969-1975) and later models (1976-1981). Always verify the specific mounting style - some lights use the original factory mounting holes while others may require drilling. Check product descriptions for year-specific fitment or contact us with your OEM for confirmation.

What's the difference between sealed beam and LED options, and which is better for my truck?

Sealed beam lights are traditional, cost-effective options that maintain the original appearance but typically draw 55-65 watts per light. LED upgrades use modern technology, drawing only 20-30 watts while producing 2-3 times more light output. LEDs last 30,000-50,000 hours compared to 500-1,000 hours for sealed beams. Consider LEDs if you want better visibility and less strain on your electrical system, or sealed beams if you're restoring to original specifications.

Do I need to upgrade my wiring or add relays when installing new lights?

For standard sealed beam replacements, your existing wiring should work fine if it's in good condition. However, if you're adding auxiliary lights or upgrading to high-output LEDs, we recommend installing a relay harness to prevent overloading original wiring. Many customers report dim lights due to voltage drop in aging wires - if your current lights are dim, consider running new 14-gauge wire from the switch to ensure full brightness.

What tools and time commitment are required for installation?

Basic headlight replacement typically takes 30-45 minutes per side with common hand tools: Phillips and flathead screwdrivers, 7/16" and 1/2" wrenches, and possibly a trim removal tool. Full auxiliary light installation including wiring can take 2-4 hours. The biggest challenge reported is accessing mounting bolts behind the grille - having a magnetic parts tray and patience helps. Some fog light kits require drilling, so have a quality drill bit set ready.

How do I ensure my lights meet DOT regulations and state requirements?

All headlights must be DOT approved - look for the "DOT" marking on the lens. Main headlights must be white, while auxiliary lights can be white or amber (amber is preferred for fog lights). Most states limit you to 4 forward-facing white lights total when on public roads. Height requirements vary by state but generally range from 22-54 inches from ground to center of light. Always verify your local regulations, especially if adding light bars or auxiliary lighting.
