LED Watermelon Lights vs Incandescent Lights: Which Upgrade is Better?

21st Feb 2025

Watermelon lights are commonly used for functional purposes like side marker lighting or cab roof lighting, and sometimes just for aesthetic appeal like grille accents or underglow effects.

They are also wildly popular at truck shows and add a ton of style to most class 8 heavy-duty trucks while serving a useful, functional purpose.

However, plenty of semi-truck drivers opt for the classic-looking glass incandescent lights as well. These lights emanate a softer and less saturated hue.

Between these two options, which aftermarket lighting upgrade is better for your big rig?

Pros & Cons of LED Watermelon Lights

LEDs are considered the industry standard, since they are more durable, longer lasting, and have a water-tight seal to prevent moisture build up.

Pros:

Longer lifespan – LEDs can last up to 50,000 hours.
Energy-efficient – significantly lower power draw than incandescent bulbs.
Brighter and sharper colors – available in a variety of hues (amber, red, orange, purple).
Durable – more resistant to vibrations and weather conditions.

Cons:

Higher upfront cost – more expensive than incandescent lights.
Some LEDs lose the classic "glow" – can look too sharp or unnatural.
Compatibility – may require additional wiring or voltage adjustments.
