What products are in the BTS Lighting best sellers collection?
The collection features truck lighting and accessories, including Alpha 360 warning beacons, glass watermelon light kits, LED marker and tail lights, a Peterbilt 389 headlight bulb kit and watermelon light brackets. Browse the listings above for the current selection.
Will these lights fit my truck or pickup?
Fitment varies by product. Check your vehicle model and year where listed, then confirm voltage, dimensions, mounting space and wiring. A vehicle-specific headlight kit and a universal light or bracket have different installation requirements.
What is the difference between single-function and dual-function lights?
A single-function light provides one lighting function; a dual-function product supports two. Check the listing for its exact operation and wiring. Dual-function does not automatically mean dual-colour, and products are not interchangeable solely because they look similar.
Do watermelon light kits include brackets and wiring?
Contents differ between kits, individual lights and brackets. Review the included-parts list and selected option before ordering. Match any separately purchased bracket or harness to the specific light and installation.
Are best sellers always in stock or on sale?
No. Best seller status does not guarantee immediate availability or a discount. Check the current price, stock or backorder notice and selected option on the product page before purchasing.
