Hi David,

I sell Vanagon headlight relay kits for $27.50 plus shipping.  That is just
over half the price generally found elsewhere on the web.  I have plenty in
stock, ready to ship if you would like a set.  There is information on my
website https://sites.google.com/site/vanagonheadlightrelays/ about the
relays and the various headlamp upgrades that have been mentioned as well.

One thing that hasn't been discussed yet is to be sure that the inside
surface of your headlight lenses are nice and clean.  This can make a
noticeable difference in the output from your current lights and only takes
a few minutes.  I used to run the Hella 80/100W bulbs
http://tinyurl.com/2vytw35 in my '87 Wolfsburg before I swapped in a set of
round headlamps from an early van.  I would say the 80/100W bulbs with a set
of relays is about the best bang for the buck you can get with stock
headlight lenses.  Since all filament based bulbs degrade over time, you
should replace your high beam bulbs as well if they are more than a year old
http://tinyurl.com/2ay5rus.  There are 100W H3 bulbs available as well, but
I would recommend the standard 55W bulbs for the high beams, since the heat
of the higher wattage bulbs in the small inner high beam lens can sometimes
lead to greatly shortened bulb life.  Be sure to check the aim of your
headlamps as well http://tinyurl.com/35kw8q9 , badly aimed lights won't give
good results regardless of the bulbs you are running.
