Led Side Marker Light Bulbs

The shell is made from aluminum, which helps draw heat away from the LEDs during operation. There are no fans or moving parts inside. The glass lens over the front chip is slightly curved, which helps direct light forward rather than scattering it broadly. The overall length is kept short so that the bulb fits into tight clearance light assemblies where longer units may not seat properly.

These LED marker lights include basic circuitry to handle minor voltage variations, which can occur in older truck electrical systems. The unit does not require an external driver box. For vehicles with CAN-bus monitoring, some installations may still need load resistors to prevent error messages, as this is a general characteristic of low-wattage LED replacements rather than a specific issue with this model.

Common applications include roof clearance lamps, side marker lights, and front or rear identification lights on trailers and box trucks. The 6000K white output provides a visible contour reference for other road users in low-light conditions. The 300LM level is adequate for marking purposes without being excessive for surrounding traffic.

Production takes place in a facility that maintains ISO9001 and IATF16949 quality management systems. Automated assembly lines are used for consistent output across batches. For wholesale buyers, the factory offers custom packaging options and logo printing services. Direct purchasing removes distributor markups, and minimum order quantities for custom orders are kept practical for smaller retailers. Inventory is held for regular dispatch to fulfillment centers supporting online and offline sales channels.
