Choosing Rear Light Bars for Your Truck
Build your rear lighting setup around the mounting points and the lamps you need. Compare complete light-equipped bars with empty cutout bars before choosing the appearance and finishing details.
Rear center light panels
Check the space available at the rear of the truck. The collection includes 33-3/4-inch center panels with different combinations of 4-inch and 2-inch light openings or installed lamps.
Cutout-only bars & panels
Choose openings that match your preferred round or oval lights. Confirm the required grommets, bezels or visors separately; an empty panel is not a complete lighting assembly.
LED lamps & finishing details
Compare the listed lamp series, lens colour and supported functions. Check the included visors, grommets, brackets and wiring rather than assuming every version includes the same parts.
Rear Light Bar FAQs
What is the difference between a rear light bar and a rear center panel?
Rear light bars and center panels provide different layouts for rear-mounted lamps. Compare the product dimensions, mounting position and number of light openings with your existing truck setup; the names alone do not confirm fitment.
Do these rear light bars include LED lights?
Some listings include LED lamps, while others supply a bar or panel with light cutouts only. Check the exact description for lamps, grommets, visors, bezels, wiring and hardware before ordering.
How do I choose the correct bolt pattern?
Measure your existing mounting points and compare them with the listed pattern. This collection includes 2-inch, 2-1/2-inch and 3-3/4-inch bolt-pattern options. Also compare the overall dimensions and available clearance.
Can I use 4-inch round lights or oval lights?
The opening must match the lamp and its mounting method. Products here include 4-inch round and oval cutout configurations, plus center panels with additional 2-inch openings. Confirm the exact opening dimensions and required grommets or other mounting parts.
Are chrome and stainless steel rear light bars interchangeable?
A finish does not determine fitment. Match the bolt pattern, dimensions, spring-loaded or fixed arrangement, and lamp configuration first. Check the specific material and finish in each listing.
Will a rear light bar fit my Peterbilt, Kenworth or Freightliner?
Do not select by truck make alone. Compare the vehicle’s mounting arrangement and dimensions with the product specifications, including any model or year restrictions. Ask BTS Lighting about an uncertain application before ordering.
What electrical details should I check before installation?
Confirm each lamp’s voltage, connector or wire arrangement and supported functions. A rear light bar may need additional wiring or mounting components. Follow the instructions for the specific product and have a qualified installer resolve compatibility questions.
Are rear light bars sold individually or in pairs?
Package quantities vary. Several spring-loaded bar listings specify a pair, while center panels and brackets have their own quantities. Use the exact product description rather than assuming that a photo shows everything supplied.
