Our semi truck turn signal lights are designed to boost visibility and enhance your rig’s safety. Whether you're replacing a cracked housing or upgrading to high-output LEDs, these lights help alert other drivers to your next move—lane changes, stops, or turns—clearly and reliably.

Turn Signal Lights for All Trucks

We carry universal turn signal lights that fit a wide range of commercial truck models, including Peterbilt, Kenworth, Freightliner, Mack, and Volvo. Perfect for: - Long-haul semi trucks. - Vocational work trucks. - Heavy-duty commercial vehicles. - Custom show rigs.

Why Upgrade to LED Turn Signal Lights?

Stock lights fade. LED upgrades shine brighter, last longer, and draw less power. Here’s what you’ll get: - High-output LED illumination that cuts through rain, fog, and night. - Amber and clear lens styles for a custom look. - Dual-function options that work as both turn signals and marker lights. - Fast response times that give other drivers quicker warning. - Plug-and-play universal fit for fast installs. These are some of the best turn signal lights on the road—designed to withstand vibration, harsh weather, and long hours behind the wheel.

Built for the Road Ahead

Every truck signal light in this category features: - Durable housings made to resist dust, water, and impact. - DOT-approved brightness and beam patterns. - Compact, low-profile designs that fit tight spots. - Long-lasting LEDs that keep your rig lit mile after mile. Pair them with commercial truck tail lights or upgrade your full lighting setup, including your truck's back-up lights and marker-clearance lights for greater visibilty all around.
