GR- Model LED Roof Cab Light Kit for Truck and Van Safety Lighting

This GR- model LED roof cab light kit is a practical exterior lighting solution designed for vans, trucks, and other commercial vehicles. It provides the essential side and rear marker illumination required for safer operation in low-light conditions, helping to define the vehicle's profile for other road users. The kit arrives as a complete set with all necessary hardware, simplifying the installation process. With a focus on durability and low power consumption, these lights are built for the demands of professional transport use, connecting directly to a standard 12-volt vehicle electrical system.
Features and Construction

The construction of this roof cab light focuses on reliable performance and straightforward fitting. Each light assembly is supplied as separate components, allowing for flexible installation that suits different vehicle roof configurations and wiring setups.
Material and Build
The primary material used is PC, or polycarbonate, known for its strength and ability to withstand impact and UV exposure, making it suitable for an exterior automotive application. The inclusion of a rubber sole acts as a critical sealing component; it sits between the light base and the vehicle's roof panel. This rubber gasket helps create a water-resistant barrier to protect the electrical connections and interior from moisture, while also providing some vibration damping from road movement.
Size and Practical Fit
The key dimensional specification provided is a boundary dimension of 83mm. This measurement likely refers to the outer diameter or footprint of the light assembly once installed, which is a useful guide for planning the placement and spacing of multiple lights across a vehicle's roof. The compact size is designed to provide effective illumination without being obtrusive. The kit supplies five complete light assemblies, offering coverage for the corners and centre of a typical cab roof as per common safety marking conventions.
Uses and Placement

Roof cab lights serve a clear safety function on larger vehicles. Their primary role is to make the vehicle's outline more visible at night, in fog, or at dusk, which is crucial for preventing accidents, especially during lane changes or on multi-lane roads.
Event or Professional Use
For commercial operators, fitting approved marker lights is often a legal requirement for vehicles over a certain width or length. This kit is directly relevant for fleet managers, owner-drivers, and vehicle upfitters who need to equip vans, lorries, utility trucks, or motorhomes with compliant external lighting. The availability of different lens colours—yellow, transparent, and smoked black—allows the lights to be matched to specific vehicle liveries or lighting regulations that may stipulate amber markers.
Everyday Home Use
While primarily for commercial use, this kit is also applicable for DIY enthusiasts or owners of larger personal vehicles like campervans or horse boxes who need to add or replace existing roof markers. The comprehensive pack of components means that all necessary parts are on hand for a single project, avoiding the need to source bulbs, seals, and screws separately.
Benefits and Buying Value

The value of this product lies in its completeness, specified longevity, and energy efficiency. It addresses the need for a reliable, maintenance-conscious lighting upgrade or replacement for work vehicles.
Reuse and Low Maintenance
The most significant maintenance advantage comes from the integrated T10 LED bulbs, which have a stated service life of 50,000 hours. Compared to traditional filament bulbs, this vastly extended lifespan means the lights are far less likely to fail between scheduled vehicle inspections, reducing downtime and the hassle of frequent bulb changes. The LED technology also draws only 0.1A of current per light, placing minimal extra load on the vehicle's alternator and battery.
Why Choose This Product
Choosing this kit provides a straightforward solution for a specific automotive need. It offers a balance of practical specifications: a defined size for planning, a choice of lens appearance, and components made from materials (PC and rubber) appropriate for the harsh external environment of a vehicle roof. The inclusion of everything needed for five lights—lenses, bases, bulbs, sockets, and screws—adds convenience and ensures component compatibility, which is a key consideration over sourcing individual parts from different suppliers.
