Description
The 42 mm festoon bulb set from Roka Solutions is a bright and durable lighting upgrade for any truck or trailer.
It is designed for 24–30 V systems and built to handle daily use in demanding environments.
Each set includes two LED bulbs, both made with 24 powerful LEDs that give a full 360° beam of light.
These bulbs replace standard 42 mm festoon lamps and provide more light with less power.
Each bulb uses only 2 watts, which keeps your electrical system efficient and cool.
The result is strong, even lighting with no dark spots.
This makes them perfect for cabins, marker lights, number-plate lamps, and accent lighting.
You can choose between Warm White and Red versions.
The warm white gives a soft and clean glow for interiors or sleepers.
The red option offers a bold accent that looks great on show trucks and custom builds.
Both versions run smoothly on 24–30 V and stay stable even with voltage changes.
Installation is fast and simple.
Just plug them into any standard SV8.5 socket.
The design is vibration-resistant and heat-stable, which makes it reliable even on long drives or in rough conditions.
Each set is sold as a pair and backed by a 1-year Roka Solutions warranty.
In addition, these bulbs help lower power draw from your alternator and batteries.
As a result, you save energy while improving light output.
Whether you are upgrading your truck’s interior or adding stylish red accents, this LED set offers long life, low power use, and a bright modern look.
