Lanuovx 3157A Amber Mini Bulb 20-Pack — 12V 475 lm Warm Amber Turn Signal & Brake Light Replacement

The Lanuovx 3157A (amber) 20-pack is a set of 12V miniature bulbs designed to replace 3157-style brake, turn signal, tail and marker lights with warm amber illumination.

These Lanuovx 3157amber bulbs come in a bulk 20-pack so you have spares for multiple fixtures or future replacements. Each lamp delivers about 475 lumens at a color temperature near 2800K, producing a warm amber output intended to improve visibility of turn and brake signals in various weather conditions. Built with quality materials and precision manufacturing, these bulbs aim to provide extended service life while fitting a range of 3157-compatible sockets used across many vehicle models.

What vehicles and sockets are these bulbs compatible with?

The bulbs are made to fit 3157-style bases and equivalent part numbers such as 3047, 3057, 3157LL, 3157K, 3457, 4057 and 4157. They are generally used in sockets designed for 12V miniature bayonet bulbs found in many cars, trucks, trailers and SUVs. Always compare the base type and electrical specifications with your vehicle before installation.

• Fits 3157 and equivalent base types (3047, 3057, 3457, 4057, 4157).
• Designed for 12V automotive systems—check your vehicle’s voltage requirements.
• Commonly used for brake lights, turn signals, tail lights, and side markers.
• Confirm fit by matching socket shape and bulb length to your application.

How bright are these amber bulbs and what color will they show on my car?

Each bulb produces roughly 475 lumens and a warm amber tone around 2800K, which creates a noticeable amber signal without appearing overly white or harsh. The amber glass/coloring provides a distinct signal color favored for turn indicators and side markers, improving contrast against red brake lights or white reverse lights.

• Approximate output: 475 lumens per bulb.
• Color temperature near 2800K for warm amber appearance.
• Amber glass ensures consistent signal color at the lens.
• Works well behind clear or amber lenses to signal turns/brakes.

What should I expect for durability and lifespan?

Lanuovx manufactures these bulbs with attention to material quality and precise assembly to extend usable life compared with cheaper, lower-grade options. While exact lifespan depends on usage patterns and electrical conditions, the bulbs are presented as long-life replacements suitable for drivers who prefer stocking spares in a multi-pack. Proper installation and stable vehicle voltage will help maximize longevity.

• Constructed from higher-grade materials for extended service life.
• Precision manufacturing aimed at consistent performance.
• Pack of 20 reduces frequency of repurchase and provides spares.
• Longevity influenced by vehicle voltage and duty cycle.

How do I choose and install the correct replacement bulb?

Start by confirming your vehicle’s required bulb part number and socket type; compare the 3157A dimensions and bayonet base to your existing lamp. Turn off power, remove the lens or housing per your vehicle manual, press and twist to remove the old bulb, then insert the Lanuovx 3157A and verify correct orientation and function. If a bulb does not illuminate, check socket contacts and fuses before replacing the bulb.

• Verify part-number compatibility and 12V requirement first.
• Follow vehicle manual for safe removal and insertion steps.
• Test the bulb after installation; reseat if it does not light immediately.
• Inspect socket and fuse if a newly installed bulb fails to operate.
