LASFIT 3157 LED Bulbs Red 2-Pack — CANBUS Compatible, High-Output with Active Cooling Fan

LASFIT CANBUS 3157 LED Bulbs (2-pack) are high-output red replacement bulbs designed to upgrade brake, tail and rear turn signals with error-free CANBUS compatibility and plug-and-play installation.

These LASFIT red 3157 bulbs modernize the look and visibility of compatible vehicles by combining a compact aluminum housing, an active cooling fan, and a dense array of high-grade LED chips. Engineered to work as a direct swap for 3157/3057/4157-style sockets, they deliver brighter red output than halogen while avoiding dashboard errors on CANBUS-equipped vehicles. The set includes two bulbs and fits a broad range of OEM applications where 3157-series lamps are used.

How much brighter are these bulbs compared with stock halogen lights?

The LASFIT 3157 red LEDs are engineered for a significant increase in visible output. With multiple premium LED chips arranged for full-angle coverage, they deliver a noticeably stronger brake/tail illumination that reads faster to following drivers.

• Up to 500% brighter light intensity vs. typical halogen equivalents.
• Approximately 4800 lumens of combined output per bulb under optimal conditions.
• 360-degree illumination pattern for consistent brake/tail coverage.

Will these bulbs trigger CANBUS or hyper-flash warnings on my vehicle?

LASFIT has integrated an upgraded resistor and driver circuitry to prevent common warning codes and hyper-flash behavior on many modern vehicles. This built-in error suppression removes the need for separate resistors in most installations.

• CANBUS-compatible circuitry to reduce dashboard error messages.
• Engineered to limit hyper-flash without extra components on compatible systems.
• Tested across numerous vehicle platforms for improved reliability.

How easy is installation and what about fitment?

Installation is simple: remove the existing halogen 3157/3057-style bulb and push the LASFIT LED into the same socket. The bulbs are designed for no-polarity insertion and to act as direct replacements for many OEM lamps.

• Direct fit for 3157, 3057, 4157 and common OEM variants.
• No-polarity design makes swapping bulbs quick and foolproof.
• Works as a direct replacement for many Silverado and similar model brake/tail/turn sockets.

How durable are these LEDs and how is heat managed?

The LASFIT 3157 uses a full aluminum body paired with a high-RPM cooling fan to manage heat and extend component life. That thermal strategy supports longer runtime and helps preserve consistent color and brightness.

• Durable aviation-grade aluminum housing for heat dissipation.
• Active 12,000 RPM turbo cooling fan to keep junction temperatures lower.
• Rated service life of roughly 30,000 hours under normal conditions.

Who is this for: These LASFIT 3157 red LED bulbs suit owners seeking a brighter, modern brake or tail-light appearance without reworking wiring or adding resistors. They are ideal for drivers of compatible trucks and cars who want a direct drop-in LED upgrade that minimizes CANBUS complications and reduces maintenance thanks to long-life components.
