Craig and all,
I agree that the stock '86 up low beams SUCKKKK!
They so drove me crazy in my old '86 westy that I almost bought Euro
H-4s at $135 a side! (Fortunately it burned up before I could buy
them.... 8-0 ).
But the problem lies in the lousy construction of the lights, not in
the wattage of the bulbs.
I've seen what one gets with the high watt bulbs and was unimpressed.
Using higher wattage bulbs is not a great solution for two reasons:
First, doubling the wattage only increases the light output by like 1/3.
Second, brighter lights don't compensate for the poor design of the
light reflectors and optics. You'll still have hot spots and poor
beam distribution.
Third: I HATE being blinded by oncoming cars with high Watt bulbs!
(okay, I know I said TWO reasons, but this just came to me! ;) )
There are few alternatives. The SA Quad Grille (which I sell) with
Hella round Vision Plus lights or H-4s is the best.
Euro H4 replacements is second best but they are expensive and is a
VW exclusive product. (I'm looking into getting a cheap source,
however).
Adding aux Fog lights will also help supplement the low beams. Hella
used to make an aux "low beam" light, but I don't know if they still
do.
Finally, I'm now a BIG believer in using a relay and running a large
gauge wire directly from the battery to the lights.
Hella claims that if the thin wire that runs through the light switch
to the lights drops the voltage only 10% (which is likely, maybe
more) from 13.8 volts to 12 you'll only have 67% of your lights
luminous intensity!!
I didn't believe this until I burned up a couple of $50 switches in
my Corrado after adding Euro driving lights and decided to try a
relay on my high beams.
I COULD NOT BELIEVE THE DIFFERENCE!! It was like I got higher watt
bulbs. The light color changed to bright white making the stock
set-up seem yellow by comparison. And this is with the STOCK 55/60W
bulbs! I then added a relay to the low beams. That was a HUGE
difference.
So, try the relay first. Then move on from there.
I'm going to start selling relays and wiring harnesses to accompany
my SA Quad grilles, but they'll work with the stock lights as well.
I hope this helps
