Frequently Asked Questions About Freightliner Cascadia 113/125 Driving Lights

Will these driving lights fit my specific year Cascadia 113 or 125?

Most aftermarket driving lights for the Cascadia 113/125 are designed to fit models from 2008-2017, with some newer options available for 2018+ models. The key difference is in the bumper mounting points - pre-2018 models typically have different bracket spacing than the newer generation. Always verify your truck's exact year and check if your bumper has been modified or replaced, as aftermarket bumpers may require different mounting hardware.

What's the difference between LED and halogen driving lights for my Cascadia?

LED driving lights draw significantly less power (typically 40-80 watts vs 100-130 watts for halogen), produce brighter and whiter light output, and last 30,000-50,000 hours compared to 500-1,000 hours for halogen bulbs. However, LED options cost 2-3 times more upfront. Halogen lights are easier to replace if damaged and work better in heavy snow conditions as they generate heat to melt ice buildup. Most drivers prefer LED for long-term reliability and visibility.

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

For most single or dual light setups, your Cascadia's existing auxiliary light circuit can handle the load, but we strongly recommend adding a relay harness for any installation. This protects your truck's electrical system and ensures consistent power delivery. For LED lights drawing under 10 amps total, you can often use existing wiring with a relay. For high-powered halogen setups or multiple light bars, you'll need to run new 12-14 gauge wire directly from the battery with appropriate fusing.

Can I mount driving lights on my Cascadia without drilling holes?

Yes, several no-drill mounting options exist for Cascadia 113/125 models. Many bumpers have pre-existing mounting tabs or slots designed for auxiliary lights. Bracket kits that clamp onto the bumper frame or utilize factory bolt holes are available for most model years. However, these may limit your positioning options. Custom mounting locations typically require drilling, but using a proper step bit and rust protection will maintain your bumper's integrity.

Are driving lights DOT approved and legal in all states?

DOT approval varies by light manufacturer and model - look for lights marked with "DOT SAE F" for fog lights or "DOT SAE D" for driving lights. However, state regulations differ significantly. Most states require auxiliary lights to be covered or disconnected when driving on public roads with oncoming traffic. Some states limit the number of forward-facing lights or their mounting height. Check your state's specific commercial vehicle lighting regulations, as violations can result in fines and failed inspections.
