Description

Genuine Ring · Part no. RU501

Photo shows the range. Size as stated.

The Ring RU501 is the everyday 501: a 12V 5W W5W capless bulb on the W2.1×9.5d base, 10mm across. It lights sidelights, tail lamps and number plate lamps on a huge number of cars, and this one is made to original quality, E-marked and sold one to a blister.

Good to know

• Is a 501 my bulb? Sidelight, number plate and interior bulbs are mostly 5W types such as the 501 (W5W) and the C5W festoon. Pull the old bulb out and check it reads W5W or 501.
• How do I get it out? Capless (wedge) bulbs push straight into their holder, while bayonet bulbs (BA15s, BAY15d and similar) push in and twist to lock. This one just pulls straight out of its holder.
• Will a 504 do the same job? A W3W (504) and a W5W (501) share the W2.1×9.5d capless base, so check the wattage on the old bulb before ordering. Fit 5W where 5W came out.

Which one?

Two 501s come as the Ring RW501; for an amber 501 in side repeaters choose the Ring RW501A.
