Additional Features2008. Rear stop lights, park lights, number plate lights and inside roof light are all LED's.

June 2011. Replaced all turning lamps with LED's and replaced the flasher unit with a
home-made moss-fet circuit, current consumption has dropped to about 0.5amps when
turning. A big saving on power from the 12v battery.

I downsize the 12V accessory battery with a Lithium-Iron type, it is trickle charged with a
5w PV panel in the rear window.

Replaced the 65/65w headlamps with high efficiency 35/35W lamps and added a small
LED in both main headlight reflectors. I have wired these LED's when the key switch is on.
These headlight LED's have already save me from one accident. Small car ... hard to see.
My Mini was first commissioned on 9th July 1998 with my first lot of VRLA batteries.
8 x 12v Sonnenschein 70A/hr.

Second lot were 8 x Optima 65A/hr.

Third bank is my present make Thunder Sky - Lithium-Ion.
