Yorkim 3157 LED Bulbs Pack of 10 — 6500K Cool White 1100 lm 12V 360° T25 Replacement

Yorkim 3157 LED bulbs are bright, cool-white 12V replacement lamps designed to upgrade reverse, brake, tail and turn lighting in vehicles that use 3157-style sockets.

These plug-and-play T25 LED bulbs replace standard 3056/3156/3157 family halogens and deliver a whiter, higher-output beam for improved visibility when reversing or signaling. Each bulb uses 18 5050 SMD chips arranged for 360-degree light, a built-in constant-current IC for stable performance, and a rated life far longer than typical halogen lamps. Before ordering, confirm your vehicle's bulb number and housing clearance to ensure a correct fit.

How much brighter are these bulbs compared with stock halogens?

The Yorkim 3157 LEDs produce up to approximately 1100 lumens per bulb at a 6500K color temperature, offering noticeably whiter and more intense light than many OEM halogen backup lamps. That increased output helps illuminate the area behind the vehicle for easier reversing in low-light conditions.

• Rated output: ~1100 lumens per bulb
• Color temperature: 6500K cool white for clearer contrast
• 18 high-quality 5050 SMD chips in 360-degree layout
• Advertised up to 300% brighter vs tested stock halogen

Will these LEDs fit my car's 3157 socket and wiring?

These bulbs are built for standard 3157-style bases and are compatible with equivalent numbers such as 3056, 3057, 3156, 3356, 4157 and others, as long as the socket and housing provide sufficient space. They operate at 12V and install like the original bulbs, but confirm the original bulb number and check clearance inside the lamp housing before purchase.

• Compatible base types: 3157 and many equivalent numbers
• Operating voltage: 12V DC
• Check housing depth and socket match before fitting
• Not all vehicles support error-free LED bulbs without modification

Do I need additional parts to prevent hyperflashing or errors?

Some vehicles detect lower current draw from LEDs and may hyperflash, blink rapidly, or show a bulb-out warning when using these as turn signals. Yorkim bulbs include a constant-current IC for dimming stability, but load resistors, an LED-compatible flasher relay, or vehicle-specific wiring adaptors may still be required for error-free operation.

• May trigger hyperflash or bulb-out warnings on some vehicles
• 50W load resistor or LED flasher often resolves hyperflash (sold separately)
• Error-free operation cannot be guaranteed for every make/model
• Recommended: test on the vehicle and add resistors if needed

How long will these LED bulbs last and how efficient are they?

Yorkim 3157 LEDs use a constant-current driver and efficient SMD chips to reduce power consumption and maintain brightness over time. They are rated for an extended service life, significantly longer than standard halogen bulbs, which lowers replacement frequency and energy use.

• Built-in constant-current IC for stable output
• Energy use much lower than equivalent halogen bulbs
• Estimated life up to 50,000 hours under normal operation
• Durable SMD construction resists vibration in automotive use

Who is this for: The Yorkim 3157 LED Pack of 10 is well suited for car owners, fleet operators, and DIY mechanics seeking a bright, long-lasting upgrade for reverse lights, backup lamps, and other 3157-base applications. If you want whiter, higher-output illumination for safer reversing or a modern look for tail and brake lighting, and you're willing to check vehicle compatibility or add a load resistor if necessary, these bulbs are a practical, cost-effective choice.
