Although you can buy a halogen bulb to fit the old style tungsten socket, you will get much better results if you replace the whole unit with a late model PX halogen unit. The process is pretty easy but it is not “plug and play”. Below are before and after shots.

./Halogen upgrade wiring changes.jpg

Above is shown the wiring from the new halogen unit. The old style connection to the headlight are crimp style connections but the new style are plug types. It is easiest to use the old style because the connections come in a standard crimping set that can be purchased at a local hardware store. All wires on the unit above will need to have the connections replaced (i.e. cut off the existing plugs and crimp on new connections) and you may need to change 2 on the scooter if you crimping kit doesn't have smaller sizes.

The wiring colours are exactly the same, so just connect colour to colour. You will need to use insulation tap to prevent short circuits.

Apart from a few minor connection changes above, the halogen unit fits into place perfectly.

The results of changing the unit proves to be very good. Much brighter daytime visibility for your scooter and at night much clearer view of the road. There was a noticably improvement over the halogen bulb/old reflector configuration. We have not measured the output though to confirm the actual difference.

Other info...

You will need to buy a W5W 12v 5W park light as it does not come with the unit. You may also need to buy a H4 12V 35/35W Halogen bulb. Note: Car H4 bulbs are 55W, which work but above the design spec (i.e. may draw power from somwhere(?) else).

I use the 55w car ones and have had no problems at all.

Excellent observation! I have recently been closely looking at the ignition/charging circuit as I have been making one from scratch. Reviewing it with this knowledge and after your comment it appears that the charging circuit is completely different to the lighting circuit (http://vespamaintenance.com/elec/diag/p200diag2.jpg).

If you hook up spot lights to the battery circuit (which I have done) it does drain the battery, however just adding a 55w replacement is drawing the extra power from somwhere else... I have updated the info.

Hmmm... more tinkering suggests although the circuits out of the reg/rect are different, they are powered by the same sigle ac input from the coil. I'll experiment some more and I'll be able to tell if battery charging is deminished if ac power used more.
