Antline 3156/3157 LED Bulbs Pack of 10 — White 54-SMD 360° Bright 12–24V Low-Power

These Antline 3156/3157 LED bulbs are high-output 54-SMD replacements that deliver bright, 360° white light for 12V–24V vehicle circuits.

Designed as direct-fit upgrades for many common automotive and RV wedge sockets, this 10-piece set uses compact 3014 LED chips to boost visibility while drawing low current. Each bulb measures 1.7" long and 0.7" diameter, runs at about 3W and 310mA, and produces roughly 400 lumens — making them suitable for tail, brake, reverse, backup, parking, and interior lighting in cars, trucks, trailers, boats and campers.

How bright are these Antline bulbs compared to stock halogen lamps?

Each bulb contains 54 3014 SMD LEDs arranged for near-complete 360° illumination, which increases apparent brightness well above typical halogen wedge bulbs. They produce about 400 lumens per bulb while using only 3W, offering improved light output with much lower power draw.

• 54 SMD chips per bulb for fuller light coverage
• Approx. 400 lumens output and 3W power consumption
• 360° design reduces hot spots and dark angles

Will these fit my vehicle’s sockets and applications?

Antline lists broad compatibility across many wedge-type part numbers (including 3056/3057/3156/3157 and related variants), so they fit most standard wedge housings used for tail, brake, reverse, and parking lights. Check your owner’s manual or existing bulb part number to confirm fit before installing.

• Direct-fit for numerous 3056/3057/3156/3157 family sockets
• Works in 12V–24V systems for cars, RVs, trailers and boats
• May require a load resistor or relay for turn signals to prevent hyper-flash

Are these bulbs durable and energy-efficient?

These LEDs draw low current (about 310mA) and operate at 12–24V DC, which means extended service life and reduced drain on battery or charging systems. Their LED construction resists shock and vibration better than glass halogen bulbs, making them well suited to mobile and off-road use.

• Low power draw (3W) for reduced electrical load
• Compact, solid-state build improves resistance to vibration
• Higher lifespan than traditional halogen equivalents

What should I know before swapping these into signal circuits?

When replacing turn-signal bulbs, the lower resistance of LEDs can trigger a vehicle’s hyper-flash or error warnings. Many installations remedy this with a load resistor or an LED-compatible flasher/relay, restoring normal flash rate and system diagnostics.

• Add a load resistor or LED flasher if hyper-flash occurs
• Test a single bulb first to confirm compatibility with your vehicle electronics
• Professional installation recommended for complex electrical systems

Who is this for? These Antline 3156/3157 54-SMD LED bulbs suit DIY vehicle owners, RV and trailer enthusiasts, and fleet operators who want brighter, lower-draw lighting across common wedge sockets. They’re ideal for anyone replacing dim halogens in tail, brake, reverse, or interior fixtures and who can follow basic fitment checks or add a resistor/relay where needed. The pack of ten makes them convenient for multiple bulbs or spare inventory, and Antline provides a one-year warranty for delivery damage or confirmed defects.
