PARTSam GTCV-0652883157 4-Inch Round Red/White LED Truck and Trailer Lights

Replacing round lights on a truck or trailer? This PARTSam kit combines red stop, turn and tail lighting with a white reverse light in each 4-inch round unit, reducing the need to source those functions separately.

The package includes two lights, rubber grommets and three-prong offset wire pigtails. A separate yellow-wire bullet plug powers the white backup light.

One important distinction: the white backup function overrides the red light when reversing. The lights are rated IP65, but the product information says not to use them under water.

Strengths

Combining red stop/turn/tail and white reverse functions makes this kit worth considering when replacing a compatible round light assembly. The same LEDs produce the two colours for their respective functions, and the included grommets and wiring components make it a more complete replacement package than buying bare light units.

Buyer feedback is positive about brightness, appearance and basic operation, although some mention that the red looks dimmer when viewed from an angle. There are also notable concerns: buyers report diodes failing, wires breaking at the back and moisture getting inside. These reports do not establish how every unit will perform, but they are relevant if long-term durability or water sealing is a priority.

It suits you if you need both red running/brake/turn functions and a white reverse light in a round truck or trailer installation. It’s not for you if you need a light intended for submersion, or if the reverse function must leave the red light active at the same time.

Key features

• Type: Two round, dual-colour LED stop/turn/tail and backup lights
• Size: 4-inch lights, overall dimensions are 5.3 inches in diameter x 1.2 inches high
• LEDs: 19 diodes per light
• Operation: 12V DC
• Red functions: Black wire for low-brightness tail/running lights, red wire for high-brightness stop and turn signals
• White function: Yellow wire and bullet-style male plug for backup/reverse, white wire is ground
• Mounting: Rubber grommets and standard three-prong offset pigtails included, described for use with about 4.7-inch standard round grommets
• Water resistance: IP65, not intended for use under water

Getting the most from it

Before choosing this kit, compare the light opening and grommet arrangement on the vehicle with the listed dimensions. The 5.3-inch overall diameter and fit with about 4.7-inch standard round grommets are useful checks, but the product details do not give a vehicle-specific fitment list. Confirm that the wiring can support the separate red and white functions, including the yellow backup-light connection.

The combination format suits a replacement where both rear signalling and reverse lighting are wanted in one round assembly. A basic red-only tail light is a simpler approach if no white backup function is needed, a different setup is necessary if the reverse light must not override the red functions. For installation, follow the stated wire roles and avoid exposing the unit to submersion.

Final verdict

This kit brings together two lights and the listed mounting and wiring parts for a round truck or trailer replacement, with the practical benefit of red signalling and white reverse illumination in each unit. The override behaviour in reverse is a real consideration, and the buyer reports of diode, wire and moisture problems temper the appeal despite positive comments about brightness and function. If you prioritize a combined light assembly and its dimensions and wiring match your installation, it may fit the job, choose a different design if underwater use or simultaneous red and white operation is required.
