Trailer lights are one of the cheapest upgrades you can make, and one of the most important. Most new trailers now ship with LEDs, but plenty of older utility, flatbed and cargo trailers still run incandescent bulbs. Here is how they compare.
Why LED lights are worth it
- Brighter and faster: LEDs reach full brightness almost instantly, giving drivers behind you more reaction time.
- Longer life: LEDs commonly last many times longer than incandescent bulbs and handle road vibration much better.
- Lower power draw: less load on your tow vehicle wiring and, on trailers with a battery, less drain.
- Sealed and waterproof: good sealed LED units resist the moisture and heat we get on the Gulf Coast.
Where incandescent still makes sense
- Very low upfront cost for a quick bulb swap
- Easy to find a replacement at any parts store
- Fine for a trailer used only a few times a year
Things to watch when upgrading
- Turn signal flash: some tow vehicles flash fast with LEDs because of the lower load. A load resistor or LED-compatible flasher fixes it.
- Grounds: a poor ground is the top cause of dim or flickering lights. Clean and tighten ground connections first, see our wiring troubleshooting guide.
- Use sealed, DOT-compliant lights. Texas requires working brake lights, turn signals and tail lights, covered in our Texas trailer laws guide.
- Run through our pre-trip checklist after any wiring change.
Cost
A basic LED tail light kit for a utility trailer typically runs from about $30 to $100, and a full light bar and marker upgrade for a larger gooseneck or cargo trailer costs more. Most owners can do the job in an afternoon with basic tools.
