LED headlights?

I use high power LEDs for rear/brake lights & dash. Tried some for sidelights but didn't like the bluish light & they were not robust - too cheap I suspect! I use LED GU10s in the house & endorse the use of specifying warm white and using best quality units, not cheap, no name bulbs. The rear bulbs were expensive (15 quid a pair?), but are much brighter than the standard bulbs and the brake light comes on instantly. Having been rear-ended in the +2 this means a lot to me! They have been in there for 5-6 years with no problems. Not sure about the legality though... no kitemark.

I find the instant extinguishing of LEDs disorientating when used in brake lamps and turn signals; I guess I'll have to get used to them and they certainly betray themselves if used on classic cars, never mind the colour of the static lights.
Positive earth polarity isn't a problem on the front lamps as they can be wired in reverse individually and real bulbs won't mind. 2 Watts per bulb is a 90% saving of battery power but the $25 hurts.

I wonder if one could fit capacitors across them to replicate incandescence??

Yes, 2000-4000 uF at 16V in parallel would provide around quarter second turning off (with a pair of 160 mA LEDs) and they are cheap, about 50p/1$US. Surge current at switch on shouldn't be a problem. Anyone got a modern car to try it on?
