When visibility on the road is low, such as overcast days or during the night, Eiko's 9004CVXL-BP ClearVision XL T4.75 lamp will shine brightly. This halogen headlight gives the proper illumination a vehicle needs for safe navigation in the dark. Featuring a proprietary coating technology that creates a truer white light, this ClearVision XL bulb enables other drivers to see the vehicle and to be aware of its presence. It is also shielded to prevent blinding of oncoming traffic. The axial prefocus HB1 (P29t) base makes it easy to replace similar bulbs on any vehicle with an HB1 (P29t) headlight plug. Designed as a direct factory replacement, this automotive headlight bulb delivers a longer, more vivid beam of light for many miles.
