Amio LED CANBUS 15SMD 2835 7.5W 1157 (P21/5W) White 12V/24V automotive bulb

The Amio LED CANBUS 15SMD 2835 7.5W 1157 (P21/5W) White 12V/24V automotive bulb is a direct-replacement LED lamp designed for vehicles with 1157/P21/5W dual-contact sockets. It delivers white light using fifteen 2835 SMD LEDs and is built to operate on both 12V and 24V electrical systems. CANBUS compatibility reduces the risk of dashboard error warnings or hyper-flashing on vehicles with sensitive electronics.

Advantages

This LED bulb provides higher luminous efficiency and lower energy consumption compared with equivalent incandescent bulbs while preserving the same dual-contact socket compatibility. Its CANBUS support improves compatibility with modern vehicle electronics by minimizing false error messages. The 15 SMD 2835 diodes offer a uniform light output and stable colour temperature suitable for brake, tail and indicator functions. The construction is compact and intended for straightforward retrofit into existing 1157/P21/5W lamp holders.

Suitable for

• Brake lights in vehicles with 1157/P21/5W sockets
• Tail/parking lights requiring a dual-contact lamp
• Indicator or turn-signal positions that accept 1157/P21/5W bulbs
• Applications in vehicles with 12V or 24V electrical systems

Key specifications

• LED type: 15 × 2835 SMD
• Power consumption: 7.5 W
• Base type: 1157 / P21/5W dual-contact
• Light colour: White
• Operating voltage: 12 V and 24 V compatible
• CANBUS compatibility: built-in resistor/driver to reduce error signals

How to use

Fit the bulb into an existing 1157/P21/5W socket by aligning the dual contacts with the lamp holder and pressing gently until it is seated. Ensure the vehicle power is switched off before installation. After installation, test the corresponding light functions (brake, tail, indicator) to confirm correct operation and absence of dashboard fault messages. If a fault indicator appears, verify the bulb seating and vehicle compatibility with CANBUS systems.

Usage recommendations

Use the bulb in dry, properly installed lamp housings and avoid prolonged exposure to water ingress. For optimal performance, replace bulbs in matching pairs on the same axle to maintain uniform light output. If error messages persist on certain vehicles, consult vehicle-specific compatibility lists or an automotive electrician before additional modifications.
