Morimoto 3156/3157 XB LED Bulbs | Resistor-Free Pair

Fitment & Features

Upgrade compatible 3156/3157 bulb applications with a pair of resistor-free Morimoto XB LED bulbs. Choose amber, white, red, or switchback output, with integrated cooling and electronics designed for CK and non-CK circuits.

Fitment & Requirements

• Application: Universal 3156/3157 bulb-family replacement. Confirm the original bulb base, socket, circuit function, physical clearance, and required output color before purchase.
• Circuit type: Manufacturer lists CK and non-CK compatibility.
• Resistor-free design: Integrated electronics are designed to avoid external load resistors and turn-signal hyper-flashing. Check operation in the actual vehicle.
• Vehicle scope: Not assigned blanket Tundra model/year fitment. A guide result is not proof these bulbs replace factory LED assemblies.

Fitment & Requirements (continued)

• Switchback: Requires a suitable dual-function socket/circuit for the intended white/amber operation.
• Output selection: Use a bulb color appropriate to the lens and intended signal function.

Features

• Output colors: Amber LED405, white LED406, red LED407, or switchback LED408.
• Cooling: Integrated fan helps control bulb operating temperature.
• LED construction: 52-chip 3030SMD design with a manufacturer-listed 1,680 raw lumens per bulb.
• Included quantity: One matched pair of the selected color.
