SEALIGHT 3157 3200LM Dual Color LED Bulb

This switchback 3157 LED bulb from SEALIGHT combines amber turn signal and white daytime running light in one unit, giving clearer visibility and simpler installation for common vehicles. It targets drivers who want brighter signaling without added resistors and reduces the chance of hyper flash, according to the manufacturer.

Key features

The bulb integrates 36 J3 chips with a 12 white to 24 amber arrangement to allow instant color switching while driving. Brightness is notable at 3200LM and the white output sits near 6000K, while the flashing amber runs around 2700K, so signals remain visible in fog or low light. A built-in intelligent driver and resistor address hyper flash for most cars, avoiding extra load resistors.

Specifications

• Name: SEALIGHT 3157 3156 Dual Color J3 Pro Max
• Power: 30W
• Output: 3200LM
• Color: White 6000K and Amber 2700K
• Type: LED switchback bulb compatible with standard 3157 3156 sockets

Benefits

Durability is improved by a full 6063 aviation grade aluminum body and a hollow base design that helps cooling. The top-mounted 15000 rpm turbine fan with intelligent temperature control supports faster heat dissipation and may extend service life. Installation is straightforward for standard sockets and the anti-hyper-flash driver reduces extra wiring work in most cases.

What it works with

SEALIGHT 3157 3156 Dual Color fits vehicles using standard 3157 or 3156 sockets, not CK circuit variants. You may want to confirm fitment if your vehicle uses a CK socket. Also, note that this pack includes two bulbs, so you can upgrade both sides at once.

Usage tips

When replacing bulbs, ensure the socket type matches and test the turn signal and DRL functions after installation. If you encounter hyper flash on an uncommon wiring setup, check manufacturer guidance and vehicle wiring before modifying circuits. Remember to avoid touching the LED surface during fitting to keep longevity intact.
