one lamp (bulbs come up in the spring
), 2 filaments.
OK, so as this is the case, could you not get some connectors/holders the same as the outer set, wire up, fit another 15/5w stop tail/bulb or (21/5w as they used to be) to the inner set of tail lamps, and then have four brake lights?
I remember a thread a while ago with a guy asking about four brake lights and somebody told him they were LED's.
I must admit, I haven't checked, but the bulb and LED look casing seems more correct
But as Moley says, they look wicked at night anyhow, just as they are - but four brake lamps would look the dogs - eh?
MMMM, worth a thought??!!
