Rear LED Brake and Tail Light Bulbs for Regulated Stop Signaling

Underground Lighting's LED brake light bulbs and red taillight bulbs fit brake, tail, and combined brake/turn signal applications in cars, SUVs, and trucks. These bulbs replace the factory halogen lamps with higher, instant illumination through the rear lens during braking, emergency stops, and heavy traffic. Brighter light output improves the visibility of the braking signals while offering a more modern appearance and lasting performance. If your vehicle uses the same rear bulb for turn signals, you might see our LED turn signal bulbs.

At Underground Lighting, our collection includes popular rear lighting socket sizes such as 7443, 7444, 7440, 3157, 3156, 1157, 1156, and BA15S. These options cover single-function brake light bulbs, dual-function brake/tail light bulbs, and brake/turn signal combinations. When shopping for bulbs like BA15S and BAY15D, ensure you get the correct socket; to do so, match the bulb base and contact points to the factory housing.

Looking for truck-specific LED brake lights and taillights? Regardless of the vehicle you own, Chevrolet Silverado, GMC Sierra, or Ford F-Series, we have various high-quality lighting options available to choose from. These bulbs fit factory housings, lenses, and reflectors for proper fitment and reliable lighting performance.

Built-In Resistor & CANbus LED Brake Bulbs

Some vehicles may experience hyperflashing, rapid blinking, bulb-out warnings, or irregular brake/turn signal behavior after switching from halogen to LED. Our collection resolves these issues with CANbus LED bulbs that feature a built-in resistor to prevent dashboard warnings and flickering. Still, your vehicle shows hyperflashing errors? Shop our LED resistors and decoders to fix load-related lighting issues.

These bulbs help stabilize rear lighting performance without extra wiring in many applications, making them a cleaner upgrade for trucks, SUVs, and daily-driver vehicles.

Why Choose Underground Lighting LED Brake & Tail Light Bulbs

  • Faster Brake Light Response Improves Rear Visibility

    LED brake light bulbs designed by Underground Lighting deliver quick illumination when the brake pedal is pressed, helping your rear stop lights respond faster than traditional halogen bulbs with filament delay.

  • High-Visibility Red Output for Rear Lighting

    Strong red light output from our red LED taillight and brake light bulbs, through factory lenses, improves visibility for the brake, tail, and stop signals.

  • Better Visibility During Sudden Stops

    Underground Lighting LED brake and taillight bulbs deliver 5X brighter illumination, improving visibility in traffic, during sudden stops, on highways, and in everyday driving conditions.

  • Helps Reduce Common Blinking Issues

    Underground Lighting offers load-corrected and CANbus-ready LED brake light bulbs with built-in resistors to reduce common LED conversion issues such as hyperflash, rapid blinking, bulb warnings, or unstable brake/turn signal behavior.

  • Long-Lasting LED Performance

    Our LED brake and taillight bulbs are carefully selected and designed to last longer, illuminate more consistently, and require fewer replacements than standard halogen bulbs.

  • Vehicle-Specific Fitment for Trucks

    At Underground Lighting, we have pre-matched LED brake light and taillight options, designed for proper fitment and quick installation in almost all vehicles, particularly Silverado, Sierra, and Ford F-Series.

How to Find the Right Brake Light Bulb for Your Vehicle?

Check your bulb number in three quick steps:

  1. Find your current brake light bulb, remove it safely from the light housing, and find the part number printed on the base. Most brake lights use common bulb sizes like 1157, 3157, or 7443.
  2. Put your car's year, make, and model into our finder tool to confirm your exact fitment. Having trouble? Look up your bulb number in your owner's manual under "replacement bulbs" or "light specifications."
  3. Choose your light bulb and check out with confidence - our guarantee means you'll get the correct bulb, every time.

LED Brake Lights & Tail Bulbs FAQs

LED brake lights don't always require resistors, but some vehicles do, particularly if the same bulb serves as a turn signal. Since LEDs consume less power than halogen bulbs, certain vehicles may display bulb-out warnings, hyperflash, or rapid blinking. If your vehicle shows any of these issues after installing LEDs, choose a built-in resistor bulb, a CANbus-compatible bulb, or a proper load resistor solution.

For most rear brake lights, red LED bulbs are usually the best choice. They work better behind red factory lenses and help in maintaining a strong, clean red brake signal. White LEDs behind red lenses can sometimes look washed out, pink, or less consistent depending on the lens and bulb design.

The correct Volvo XC60 brake light bulb varies by model year, trim, and rear lamp setup. Some XC60 models use a P21W-style brake light bulb, while others may have different rear lighting configurations. The best ways to verify fitment are to check the number on the existing bulb, consult your owner's manual, or contact Underground Lighting with your XC60's year, model, and trim. 

If your LED light bulb breaks, switch off the vehicle and the lights first. Let the bulb cool, put on the gloves, and carefully remove any broken pieces from the housing or socket. Never install a cracked or damaged LED bulb, and don't force the bulb base if it's stuck. If the socket, wiring, or housing is damaged, contact a lighting expert before installing a replacement.

Fast blinking usually happens when the vehicle detects a lower electrical load after switching from halogen to LED. This is common when the brake light bulb also functions as a rear turn signal. A built-in resistor LED bulb, CANbus-ready bulb, or external load resistor may be needed to stabilize the signal.

A bulb-out warning can appear on the dashboard after installing LED brake lights. Because LED bulbs use less power than factory halogen bulbs, some vehicles interpret the lower draw as a failed bulb, even when the LED is working properly. In this case, a CANbus-compatible LED bulb or a load-corrected option for your vehicle may be needed.

Yes, many LED brake light bulbs are designed to replace factory halogen bulbs in the original housing. Make sure that you select the correct bulb size, socket type, color, and feature set for your vehicle. Some vehicles may also require CANbus or built-in resistor bulbs for proper operation.

Most LED brake light bulbs cost between $34.99 and $69.99 per pair. Basic red LED taillight bulbs are usually on the lower end, while built-in resistor, CANbus-ready, and no-hyperflash LED brake light bulbs are usually priced higher.

The final cost depends on the bulb size, rear lighting function, and vehicle fitment. A simple brake-only bulb may cost less than a dual-function brake/tail or brake/turn signal bulb.

The socket type depends on your vehicle’s factory bulb and rear light housing. Check the base of your current bulb and compare the contact points, locking pins, and part number before ordering. If the base does not match, the bulb may not fit or may not work correctly.

A 3156 bulb is usually single-function, while a 3157 bulb is commonly dual-function. They are not always interchangeable because the contacts and lighting functions can differ. If your vehicle requires brake and taillight operation from one bulb, use the correct dual-function bulb listed for your application.

Not always. Some vehicles use separate bulbs for brake lights, taillights, and turn signals. Others use a single dual-function bulb for brake/tail or brake/turn-signal operation. Always match the replacement LED bulb to the exact function and socket used in your vehicle.
