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.
2. The S1 Elise Service manual (Publication Part Number A111T0327J) lists the high level brake light bulb as an 11W 891. Assuming this is a Lucas bulb number, it is effectively a G4 halogen capsule and 11W seems rather high. An actual 2000 model car contains four W5W (501 wedge) bulbs.

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.
