I Features

The GT1505-D-WY is a compact 5 inch modular light bar built for users who want a slim housing, practical serviceability, and flexible white and yellow output in one unit. Its short length makes it suitable for positions where installation space is limited, such as front bumpers, grilles, roof-edge mounts, and other auxiliary lighting points that do not leave much room for a bulky bar. Even with its compact format, this model still delivers a driving beam, backlit styling, 9–48V DC compatibility, and a structure designed around modular connection, thermal control, and sealed durability.

LINKABLE LED LIGHT BAR DESIGN

One of the most distinctive features of the GT1505-D-WY is its soldering-free modular construction. Instead of treating the light bar as a single hard-to-service unit, this design focuses on convenient linking and easier replacement. That makes assembly more straightforward and also improves maintenance practicality after installation. If one section is damaged, the faulty module can be addressed without the same level of waste associated with replacing a full traditional bar. For buyers who care about after-sales service, parts replacement, and long-term usability, this modular structure adds real value beyond simple light output.

HIGH POWER OUTPUT

This model uses 2 × 30W 4575 LEDs for the main light and 2 × 0.5W LEDs for the backlit effect. It supports three operating states: white, yellow, and W+Y. Rated power is 22W ± 10% in white, 22W ± 10% in yellow, and 44W ± 10% in W+Y mode. The measured light output is 2160LM ± 10% in white, 2395LM ± 10% in yellow, and 3964LM ± 10% in W+Y. The driving beam pattern is designed to project usable light down the road while keeping the compact body format. Reported 1 lux reach is 135 meters in white, 153 meters in yellow, and 162 meters in W+Y mode.

38.1MM ULTRA SLIM

A major structural advantage of the GT1505-D-WY is its 38.1 mm ultra-slim profile. This reduced height helps the bar fit into mounting positions where thicker housings may look oversized or become more difficult to package cleanly. A lower profile can also support a neater front-end appearance while making it easier to integrate the lamp into modern vehicle builds that prioritize a compact, streamlined look. For distributors and builders working with limited installation space, the slim body makes this model easier to position without giving up the visual appeal of a dedicated auxiliary bar.

INTELLIGENT TEMPERATURE CONTROL

The GT1505-D-WY is designed with intelligent temperature control to improve operating stability. Thermal management is not only about keeping the housing cooler to the touch. It also matters because heat directly affects output consistency, component stress, and long-term reliability. By managing temperature in a more controlled way, the light can reduce overheating-related risk and maintain more dependable performance during sustained use. This is especially important for auxiliary lighting that may remain on for extended periods in work, trail, weather, or utility applications where reliability matters as much as brightness.

WATERPROOF RATING

With an IP67 protection rating, the GT1505-D-WY is built for environments where water, dust, and road contamination are part of normal use. A sealed housing structure helps the unit handle rain, wash-down conditions, and everyday exposure to dirt and moisture. For auxiliary lamps mounted low on the vehicle, this is especially important because these positions often see spray, mud, and impact from the driving environment. The sealed design works together with the slim modular body to support real-world durability without changing the clean external shape of the bar.

CORE PARTS BREAKDOWN

The internal structure combines several practical elements that support durability and stable use. The housing is a one-piece die-cast aluminum alloy body, which helps with strength and heat dissipation. The main light source uses customized 4575 LEDs, while the backlit section adds a visual signature when the main beam is off or when a styling effect is preferred. The sealed structure includes dedicated sealing components, and the built-in driver board is arranged around temperature-controlled operation for more stable electrical management. Together, these core parts give the GT1505-D-WY a balanced profile of compact size, serviceable modular design, and dependable auxiliary lighting performance, backed by a 2-year warranty.
