Design Notes

The X1/9 uses a fairly standard taillight bulb configuration, with only single filament bulbs being utilized for the rear lighting- all but one of them being a standard 1156 bulb (or equivalent- more on this later). Running lights are handled by a lower wattage bulb, which is a 5w 5007 (again, or equivalent) . All of these bulbs, or their equivalents, are easily available at Auto Parts stores.

The reflectors are simple molded plastic with a layer (although quite spotty) of chrome paint. Over time, this chrome finish can wear off, fade, or crumble, exposing the not-too-reflective plastic below. Duplicolor makes a chrome spray paint which can easily remedy this, and restore the performance of the reflector housings.

Original Specs

Many different bulbs will fit and work in our BA15S sockets, but I highly advise that when using halogen bulbs, you stay close to the original wattage specified for each bulb. In the case of the X1/9, that is 21W for the Brake, Reversing, and Turn signal Lamps. The rear running light (headlights on, brake not depressed) is a 5w bulb, also using the BA15S socket.
