# thanks - this is true... but they're £300 and sum of parts costs about £30
so you can see why i'd rather make my own?
its 12v 3w
i'll get some links of what i propose to use (cheaper on ebay!)
please hold - thank you for your indepth reply - woo!
battery
bulb ideally 10degree beam
and i've got a bulb holder (from a broken light) - i'm wondering if that bulb has a regulator in it or if the transformer would have it? (as im not using the transformer!)
edit : i haven't done surface mounted circuitry since i was at school! mmm acid bath

# Looks like all you need is that bulb.
It has a wide-range (11 - 16 V) input so it obviously already has some kind of current limiting in it. As the 3 LEDs are no doubt in series, even if they're using linear regulation it'll still be about 75% efficient in terms of getting power to the LEDs.

Problem solved!

Mmmmm acid bath.

# ahh i was wondering about that
so in theory
battery - switch - bulb holder - that led/bulb is all i need?

# Yep, that should be dandy.

# otherwise its
battery, switch, 3 led, lenses, 3 x that board and something to put it all in

# That board...
... will drive three one-watt LEDs in series if you're using a 12V source, so you only need one.

# oo I like the sound of that!
Send photos, my Dad will love it as he had a fairly hopped up '7 special as his first car :o)

btw, you've just challenged me to a race and the morris is going to get quicker this year ;o)

# While I'm here...
... know any good web hosts?

I need php5, an sql database, a couple of hundred meg of space, and a moderate amount of bandwidth... from someone reputable.

# actually no i don't
but im sure some other b3taians will know (have you seen my website? no hosting at all - lol)

# Dreamhost
are cheep and pretty good. I use them to host fairly big stuff like Kittenwar, and lots of smaller stuff too. Referral linky.

# Cheers.
I like the way their splash page has a picture of a seemingly-dead fat kid on it ;o)

# Yes, they kill a fat kid for every ten
new sign-ups, it's a great marketing incentive.
