(Home) Headlamp problem

I have a 1990 Townace turbo diesel. Headlamp on drivers side will work only on full beam. Does that mean I have to replace the whole unit (is it a "sealed beam" headlamp) ? or is there a bulb I can replace and if so how ?
many thanks

Bulbs are standard, and replaceable. Take off the access panel under the dash, the bulb is behind... - (#2150) david miller, 7 Feb 02

Follow on to David's post, the bulb is a standard part, any car accessory shop will know it as a 472 bulb. 60/55w. HTH. Regards Rob. - (#2155) Rob Drinkwater, 7 Feb 02
