Halfords 501 W5W Car Bulb

The Halfords 501 W5W Car Bulb Twin Pack provides dependable and consistent illumination for your vehicle. Developed to ECE Regulation 37 standards, these bulbs offer up to 25% longer life than standard Essentials 501 W5W bulbs. Designed for panel, interior, side, or tail light applications, they deliver reliable performance and brightness you can trust.
