Buying Guide

Match the bulb socket and size

Confirm your vehicle's required socket type (e.g., 7443, 3157, 7440) to ensure fit and proper electrical contact

Check CANbus and resistor needs

Choose CANbus-ready bulbs or units with built-in resistors for vehicles that monitor bulb load to prevent error codes or hyper-flash

Pick the right color temperature

Amber 2700K is standard for turn signals, while white LEDs suit reverse or backup lights and red is required for brake/tail applications

Verify brightness and lumen output

Compare lumen ratings and user feedback on visibility—brighter isn't always better if it causes glare or triggers vehicle electronics

Consider build quality and heat management

Look for bulbs with good heat dissipation and durable housings to prevent early failure, especially in LED retrofit applications
