My Seven is 1929 fabric saloon and has the BS15 holder for 6V 25W single terminal filament bulb with no dip. Looks as if the "dip" is achieved by switching off the "main" beam and leaving the sidelight bulbs in the reflector on. Dazzling - not!! Is there a similar bayonet fitting 15mm LED which would suit with at least as much or more light available from the lights as they are. Not keen to mess about with the bulb holder if possible. Any advice appreciated.
