1. The original S1 Elise Service manual (Publication Part Number A111T0327J) lists the reversing light bulb as a 21W SCC BA15 rather than the 5W part listed above. This matches the P21W found when replacing the reversing lamp on a August 1999 S1. Both options use the same bayonet fitting, the 5W has a smaller glass part. The higher wattage bulb will pull 1.75A and is independently fused at 3A so is appropriate for the wiring. 21W is more normal for a modern reversing lamp. Not clear when the 5W parts were fitted or if this is an error.

Light Upgrades

The standard headlights on Elises/Exiges are rather rubbish. A number of owners opt to upgrade the bulbs to High Intensity Discharge lamps.
