Hi,

My Elise brake lights turn on themsleves, when its parked and the key is out of the ignition. Obviously this drains the battery. How do I stop this?

From the circumstances you explain it is possible that the problem is the ABS unit.
It could simply be that ABS ECM terminal #18 is somehow touching the adjacent terminal #24. Bent terminal, loose wire strand or some other short between those terminals may cause your problem.
