to a halogen headlamp
6 volts and 25 watts the headlight on a smallframe Vespa is never
going to dazzle oncoming drivers. In fact, without decent streetlighting
you're screwed, as you can't actually see a bloody thing with
Beedspeed will sell you a replacement Bosch halogen headlight,
which should provide a much better light. The bulb you need is
a Bosch BA20D 6V 25/25W Halogen Clear. This picture shows a blue
you need to remove your headlight. to do this, locate the bolt
under the headset.
have a headlight rim, which should be removed now. The nut is tiny, so
just grip it with needle nosed pliers and unscrew the joint until the rim
slips off. The headlight bolt can then be loosened with a 10mm spanner. You
don't need to completely remove the bolt.
with the headlight removed you can see two clips (one of which
is highlighted here) that hold the bulb in place.
flip these open, making sure you don't drop the headlight shell!
you can see the bulb. Note the orientation. There's a little
cutout in the black backing which should be uppermost when the
light is in the headset. You can see it in the picture above
just to the left of the highlighted area. Make sure when you
put the new bulb in it is oriented the same. You can also see
the two little tabs on the headlight shell. these slot into two
matching slots on the inside of the headset, at the top.
remove the bulb push it up a little and twist anticlockwise.
You can see where the pins are that locate it so this is easy.
insert the new halogen bulb, reverse the process to fit it all
back together. You should align your headlight height when you
tighten up the bolt. To do this you need to make sure your tyre
pressures are correct and you are on some level ground, with
a wall 5 metres in front of you. Clearly mark a point on a wall
about 88-90cm up from the ground, and set the throttle about
1/3rd open. with yourself or someone on the scooter, and the
kickstand up adjust the beam direction so that it's concentrated
on the spot you've marked, and tighten the bolt. the setting
should be valid for 1 or 2 people on the scooter as long as you
had the correct tyre pressure, but remember you need a higher
pressure with 2 people on.
when you ride your scooter at night it's a whole world of difference.
You can actually see where you're going now! You might even dazzle
people, so now's the time to figure out which is dipped beam
and which is main beam ;-)
