LED roof cab marker light for commercial vehicles with 5-piece kit including T10 LED bulbs, available in yellow, transparent, or smoked black polycarbonate lenses measuring 83mm boundary dimension, 12V operation at 1.2W power
Commercial Vehicle LED Roof Cab Marker Light Kit with 83mm Polycarbonate Lenses

This comprehensive five-piece kit provides complete roof cab marker lighting for commercial vehicles including trucks and lorries. Each kit contains all necessary components for installing five marker lights: polycarbonate lenses, mounting bases, T10 LED bulbs, wiring sockets and fastening screws. The 12V operation matches standard vehicle electrical systems while the 1.2W power rating ensures efficient illumination without excessive battery drain. Choose between yellow, transparent or smoked black lens options to match vehicle styling or visibility requirements.
Features and Construction

The GR- model cab marker lights feature practical design elements suitable for exterior vehicle applications. The 83mm boundary dimension provides a balanced footprint for roof mounting while maintaining sufficient light output. Each component serves a specific function within the complete lighting system.
Material and Build
Polycarbonate lenses offer impact resistance against road debris while maintaining clear light transmission in the chosen colour option. The rubber sole components provide vibration damping between the light housing and vehicle mounting surface, reducing wear from road vibrations. This material combination creates a housing that withstands typical commercial vehicle operating conditions while sealing against moisture ingress.
Size and Practical Fit
The 83mm boundary dimension represents the outer measurement of the light housing, providing a reference for installation planning and spacing between multiple units. This measurement ensures compatibility with standard mounting positions on commercial vehicle cab roofs. The compact design maintains functionality without excessive projection that might catch on overhead obstacles or create excessive wind resistance during highway driving.
Uses and Placement

Cab marker lights serve multiple purposes on commercial vehicles beyond basic illumination. Their positioning and colour selection contribute to both safety and regulatory compliance in various operating environments.
Event or Professional Use
For commercial fleets and transport companies, consistent marker lighting helps identify vehicles within a coordinated fleet. The yellow lens option provides high visibility in low-light conditions while the smoked black offers a more subdued appearance for executive transport vehicles. The included T10 bulbs with 50,000 hour service life reduce maintenance frequency across multiple vehicles, lowering operational downtime for fleet managers.
Everyday Home Use
While designed for commercial applications, these lights suit larger recreational vehicles, motorhomes, or restoration projects requiring period-correct marker lighting. The comprehensive kit approach eliminates searching for compatible components, making them suitable for DIY enthusiasts restoring classic trucks or customising personal vehicles. The three colour options allow matching existing vehicle trim or creating visual contrast according to personal preference.
Benefits and Buying Value

The complete kit approach and long-life LED components create practical advantages beyond basic illumination functionality. These elements combine to provide reliable performance with reduced maintenance requirements over time.
Reuse and Low Maintenance
The 50,000 hour rated service life for the included T10 LED bulbs translates to years of typical vehicle use before replacement becomes necessary. This extended lifespan reduces the frequency of bulb changes, particularly valuable for vehicles that operate frequently or in hard-to-access roof positions. The polycarbonate lens material maintains clarity over time without significant yellowing or degradation from UV exposure.
Why Choose This Product
This kit provides all necessary components for installing five complete cab marker lights without requiring separate purchases of bulbs, sockets, or mounting hardware. The 12V operation ensures compatibility with standard vehicle electrical systems while the 1.2W power rating represents efficient energy use. The three lens colour options accommodate different visibility requirements and aesthetic preferences without needing to source separate components.
