12V-24V Truck Side Warning Lights for Vehicle Modification - SMD LED Trailer Side Marker Lights in Red, Yellow, White, Blue, or Green
12V-24V SMD LED Trailer Side Warning Lights in Five Colour Options

These compact trailer side warning lights provide essential visibility enhancement for commercial trailers and vehicle modifications. With a 3W SMD LED light source and wide 12V-24V voltage compatibility, they integrate with most standard vehicle electrical systems without modification. The five available colour options - red, yellow, white, blue, and green - allow for custom signalling configurations based on specific safety requirements or regional regulations. The 3000K colour temperature ensures consistent light output across all colour variants, while the PVC housing offers basic weather protection for exterior mounting applications.
Features and Construction

The W-SMD model side lights combine practical specifications with straightforward installation requirements. Their compact design and standard voltage range make them suitable for various commercial vehicle and trailer applications where side visibility enhancement is required.
Material and Build
The exterior housing is constructed from PVC material, providing a basic level of weather resistance for exterior mounting positions. This material choice contributes to the light's 9.6 x 2 x 1 cm dimensions, creating a compact profile that minimises visual intrusion on vehicle sides. The SMD LED technology provides the 3W light output with relatively low power consumption compared to traditional bulb-based marker lights.
Size and Practical Fit
With dimensions of 9.6 centimetres in length, 2 centimetres in height, and 1 centimetre in depth, these lights offer a low-profile mounting option for trailers and vehicle modifications. The compact size allows installation in tight spaces along trailer sides, bumpers, or modified vehicle panels where traditional larger marker lights might not fit. The mounting flexibility supports various safety and compliance applications without requiring significant vehicle modification.
Uses and Placement

These side warning lights serve multiple purposes across commercial and modified vehicle applications. Their specification-driven design focuses on practical implementation rather than aesthetic considerations, making them suitable for functional safety enhancement.
Event or Professional Use
For commercial trailer operations, these lights provide supplementary side marking that enhances visibility during night operations or low-light conditions. The five colour options allow configuration according to specific regulatory requirements - red for rear/side markers, amber/yellow for side warning lights, white for forward-facing side markers, or blue/green for specialised signalling applications. The 12V-24V voltage range ensures compatibility with various commercial vehicle electrical systems without requiring additional voltage regulation.
Everyday Home Use
For personal trailer owners or vehicle modification enthusiasts, these lights offer a straightforward solution for adding side visibility to camping trailers, boat trailers, or modified utility vehicles. The compact dimensions minimise the visual impact on smaller trailers while still providing necessary warning illumination. The PVC housing material provides sufficient durability for typical recreational use without the complexity of more specialised automotive lighting materials.
Benefits and Buying Value

The practical specifications of these side warning lights focus on straightforward implementation rather than premium features. Their value derives from meeting basic visibility requirements with minimal installation complexity.
Reuse and Low Maintenance
The SMD LED light source typically requires less frequent replacement than traditional filament bulbs, though specific lifespan data isn't provided in the source specifications. The PVC housing offers basic protection against weather elements, though no specific IP rating or water resistance claims are made in the available data. Standard automotive electrical connections facilitate straightforward replacement if needed.
Why Choose This Product
These lights provide a specification-matched solution when compact dimensions, multiple colour options, and standard voltage compatibility are primary requirements. The 9.6 cm length fits applications where space is limited, while the five colour choices allow customisation based on specific signalling needs. The 3W power rating balances visibility with reasonable electrical load for most vehicle systems. When these measurable specifications align with your trailer or vehicle modification requirements, this product offers a functional solution without unnecessary complexity.
