H7 Bulb (PX26d)

H7 bulbs (PX26d) are used in car headlights. They belong to the group of conventional light sources and halogen lamps.

They have a better concentrated luminosity than an H4 car lamp. That is why H7 bulbs are up to 150 percent brighter, because they bring the light onto the road in a more concentrated way.

The designations on the base or translated comprehensibly from the operating instructions are:

H1 = Standard low beam or high beam (Philips H1).
H3 = Standard vehicle lighting
H4 = Car halogen lamp H4 for standard low beam or high beam with double beam
H7 = Standard low beam or high beam with 12 V/55 Watt
H6 = protruding pin at base
T4W/R5W = for instrument panel illumination
P21W/P21YW = indicator light for white, transparent or orange indicator lenses
W1 – W 5 W = indicator lights on the dashboard of the vehicle
