What's the difference between LED and halogen spot lights, and which is better for my truck?
LED spot lights typically produce 3,000-6,000 lumens while drawing only 20-50 watts, compared to halogen lights that produce similar brightness but draw 100-150 watts. LEDs last 30,000-50,000 hours versus 500-1,000 hours for halogens. While LEDs cost more upfront ($50-$200 per light), they save money long-term through lower power consumption and replacement costs. Choose LED for daily drivers or work trucks, and consider halogen only if you need the lowest initial cost and use lights sparingly.
Will universal spot lights fit my truck's existing mounting points, or do I need to drill new holes?
Most universal spot lights require custom mounting and drilling. Standard mounting brackets typically fit 2-inch to 3-inch diameter tubes or flat surfaces with at least 4 inches of clearance. Common mounting locations include mirror arms, cab roof, bumper, or grille guard. You'll need to drill 2-4 holes per light (usually 8mm or 5/16-inch). Some lights include adjustable brackets that fit existing auxiliary light mounting points on Peterbilt 379/389, Kenworth W900/T680, and Freightliner Cascadia models from 2008-2024.
Are these spot lights DOT approved for on-road use, and what are the legal requirements?
Most spot lights are marked "For Off-Road Use Only" and are not DOT approved for on-highway driving. Federal regulations require auxiliary driving lights to be covered or disconnected when meeting oncoming traffic. Some states prohibit more than 4 forward-facing white lights total. Check your state's specific regulations, but generally, spot lights must be wired to a separate switch (not connected to headlights) and aimed below the horizon line. Many drivers wire them through a relay to only operate with high beams to ensure compliance.
What amp draw should I expect, and will I need to upgrade my truck's electrical system?
LED spot lights typically draw 2-4 amps each at 12V (4-8 amps for a pair), while halogen lights draw 8-12 amps each. Most trucks can handle 2-4 LED lights on existing circuits, but adding more than 20 amps total load requires running dedicated 12-gauge wire from the battery with an appropriate fuse or relay. For 6+ lights or mixed LED/halogen setups, consider adding a auxiliary fuse box. Always use weatherproof connectors and include a 15-30 amp fuse or circuit breaker based on total load.
How do I prevent water intrusion and corrosion on universal spot lights in harsh weather?
Look for lights with IP67 or IP68 waterproof ratings, which means they're sealed against dust and can handle water immersion. Apply dielectric grease to all electrical connections before assembly. Use stainless steel mounting hardware instead of the often-included zinc-plated bolts. Seal mounting holes with silicone or rubber gaskets. For maximum protection, add a bead of clear RTV silicone around lens edges after 6 months of use when factory seals may start degrading. Replace any lights showing internal condensation immediately, as this indicates seal failure.
