Frequently Asked Questions About Volvo Lighting

Will these lights fit my specific Volvo truck model and year?

Most aftermarket lights are designed to fit Volvo VNL models from 2004-2017 and VNM models from 2011-2017. However, fitment can vary between specific light types. Headlights typically have the most model-specific requirements, while marker lights and auxiliary lights often have universal mounting options. Always check the product description for your exact model year, and note that 2018+ VNL models often require different specifications due to redesigned mounting points and electrical connections.

Do I need to splice wires or modify my truck's electrical system?

Many LED upgrades are designed as plug-and-play replacements that connect directly to your existing wiring harness without cutting or splicing. However, adding auxiliary lights like light bars or fog lights typically requires running new power wires and installing a switch or relay. Headlight conversions may need resistors or CANbus adapters to prevent dashboard error messages. We recommend having a multimeter handy to verify proper connections and voltage.

How long do LED lights actually last compared to standard halogen bulbs?

Quality LED lights typically last 30,000-50,000 hours compared to 500-1,000 hours for halogen bulbs. This translates to roughly 5-10 years of normal commercial use. However, cheaper LEDs may fail within 1-2 years due to poor heat dissipation or low-quality drivers. Look for lights with aluminum housings, quality heat sinks, and warranties of at least 2 years for the best longevity.

What's the difference between DOT approved and off-road lights?

DOT approved lights meet federal standards for on-road use, including specific beam patterns, brightness levels, and color temperatures (typically 3000K-6000K for headlights). Off-road lights often exceed these brightness limits or use non-compliant beam patterns. Using non-DOT lights on public roads can result in tickets and failed inspections. All marker lights, turn signals, and headlights must be DOT approved, while auxiliary lights mounted above the headlight level can be off-road rated.

Why are my new LED lights flickering or causing warning lights on my dashboard?

Volvo trucks with computer-controlled electrical systems may interpret the lower power draw of LEDs as a burnt-out bulb, triggering warning lights or causing flickering. This is especially common with 2008+ models. The solution is to install load resistors or CANbus-compatible LED bulbs that simulate the power draw of traditional bulbs. For turn signals, you may also need to replace your flasher relay with an LED-compatible unit to maintain proper flash speed.
