360° Illumination with Two SMD LED Types

The CN360 BRS Series 1157 LED signal bulbs feature a 360° beam angle and a combination of 2835 SMD and 4218 SMD LEDs. Each bulb contains eight LEDs of each type, giving a total of 16 LEDs. The light sources are arranged around the lighting head to provide illumination in multiple directions within the vehicle's lamp housing.

This surrounding LED layout is a defining feature of the BRS design. It distributes light around the bulb rather than concentrating the entire output at one point. The final appearance of the illuminated lamp also depends on its reflector, lens, and housing, so the bulb should be selected to suit the complete lamp assembly.

Protective Cover with Ventilation Openings

A protective cover surrounds the LED assembly, helping shield the light sources from direct contact. Openings in the cover promote air circulation as part of the bulb's heat dissipation design. The cover brings protection and ventilation together around the lighting head while allowing light to pass into the surrounding lamp housing.

The BRS construction combines this covered LED head with a compact body and an 1157 base. When checking fitment, consider the complete bulb shape and the available clearance beneath the lamp cover. Space around the body should also be taken into account when matching the bulb to the original lighting position.

Non-Polar Design with an 1157 Base

The BRS 1157 bulbs feature a non-polar electrical design, removing the need to match positive and negative polarity at the bulb connection. The base must still match the vehicle's bulb holder and contact arrangement. Checking the original bulb specification helps establish the correct mechanical and electrical fit before replacement.

The operating voltage range is DC 11–18V. High and low brightness modes are provided for compatible lamp circuits, with separate current ratings for each mode. The way these modes are used depends on the vehicle's wiring and the function of the lamp position.

High and Low Brightness Operation

At a test voltage of 13.5V, the white version has a high-mode input current of 0.50 ± 0.06 A and a low-mode input current of 0.09 ± 0.01 A. The yellow and red versions each have a high-mode input current of 0.40 ± 0.04 A and a low-mode input current of 0.10 ± 0.01 A.

These separate ratings distinguish the operating modes and color options. They allow the electrical specification of the selected bulb to be checked against the intended application. Both brightness modes should be checked after fitting to confirm that the lamp responds correctly to the vehicle's controls.

Three Light Colors for Compatible Lamp Applications

The BRS Series 1157 range offers white, yellow, and red light. Listed luminous flux is 700 lm for white, 440 lm for yellow, and 130 lm for red. Each figure belongs to its respective color, while all three versions share the 16-LED configuration, 360° beam angle, and DC 11–18V operating range.

Applications across the range include tail lights, brake lights, back-up lights, and rear fog lights, depending on color and vehicle fitment. Select the bulb according to the original lamp's function, lens color, socket, and electrical requirements. The available colors are not interchangeable across every lamp position. Matching these details helps identify the appropriate BRS 1157 bulb for the intended use.
