How to Choose LED Marker Lights for Your Semi Truck
LED Marker Lights — A Must-Have Upgrade
LED marker lights are one of the most popular and affordable upgrades for any semi truck. They're brighter, last longer, and draw less power than incandescent bulbs. Plus, there are dozens of styles to choose from — so you can customize your truck's look exactly how you want.
Popular Marker Light Styles
Watermelon Lights
The classic rounded marker light with a distinctive ribbed lens pattern. Available in amber, red, clear, and multi-color options. These are the most popular style among owner-operators.
Mini Marker Lights
Small, low-profile LED lights that mount almost anywhere. Great for accent lighting along the frame, sleeper, or trailer.
Rectangular Marker Lights
Standard DOT-compliant side markers. The Saber series from United Pacific offers a unique slim design with high light output.
Colors & DOT Compliance
- Amber: Required for forward-facing and side markers (front of center point of vehicle)
- Red: Required for rear-facing markers (behind center point)
- Clear lens with colored LED: Popular for show trucks but check your state's regulations
How Many Do You Need?
A typical marker light upgrade uses 10-20 lights depending on how many you're replacing and whether you're adding accent lights. Most drivers buy extras — they're inexpensive and great to have as spares.
