Re: [ST] Spastic turn signals



I actually don't think that the motivation to change turnsignal bulbs to
LEDs has much to do with saving power, or money for that matter.  They
look cool (you get to use a clear lens too) and they are much more
dependable than lightbulbs.  But the light that they throw tends to be
quite directional.  The latest incarnations are likely to equal or
exceed the intensity of the bulbs they replace.  The website that was
offered up earlier mentioned that LEDs turn on about 20% faster than
bulbs.  This might be important for a stoplamp, but I doubt that the
improvement would be enough to actually make a difference in an
emergency.  Sounds good though  =8o)
