Glass vs Plastic — There’s No Comparison

Built differently. Performs differently. Designed for real trucks.

Plastic Lights

Sealed unit design
Traps moisture over time, leading to internal condensation.
LED failure = full replacement
Burnt-out LEDs require replacing the entire light.
Vulnerable to road debris
Impacts often damage the housing, meaning another complete replacement.
Lower light output
Reduced clarity and intensity compared to LED globes in glass watermelons.
Budget appearance
Can look flat or out of place in high-visibility areas.
Entry-level solution
Affordable option, but not designed to stand out.

Ground Effects Glass Watermelons

Serviceable modular construction
Glass, seals, bezels and globes are individually replaceable.
Lower long-term ownership cost
Upgrade LED colour or output without replacing the full assembly.
Tough glass construction
Built to handle harsh road conditions and debris.
Gasket & breather valve system
Actively reduces condensation and moisture build-up.
Premium finish
Designed to look right on bull bars, chassis rails and show builds.
Signature glow & rotation patterns
Creates a standout effect plastic housings can’t replicate.

Plastic lights are built to be replaced. Glass watermelons are built to be maintained.

Questions we get all the time...

Yes. Glass watermelons offer better light output, higher heat resistance, and a premium finish. Unlike sealed plastic units, glass systems use gaskets and valves to reduce condensation and allow components to be replaced instead of the entire light.

All Ground Effects Lighting products are tested on real working trucks in real conditions — including long-haul highway use, weather exposure, and high-vibration installs.

No. Our kits are designed as plug-and-play systems using relay-controlled power and pre-terminated connectors. Basic wiring knowledge is all that’s required, and diagrams are supplied.

We back our products with a clear warranty and return guarantee. Because glass systems use replaceable components, most issues can be resolved without replacing the entire light.

Yes. We offer all major payment options including flexible payment options including Afterpay and PayPal Pay in 4, so you can build now and pay over time.
