80/100 headlight upgrade report

Greetings,
I put in a Napa 80/100 headlight bulb (Wagner # BP1210 / H4
Auxiliary Off Road). As a test I left in the stock 10A fuse and
drove for an hour in city traffic with the high beam on. The
ambient temp was ~ 60F. It didn't blow, so I'm assuming that the
OEM circuit/switches can handle the load safely. Afterwards I
upgraded to a 15A fuse.
I haven't checked the lamp socket yet. The Big Cee FAQ mentions
that some folks have problems with melted sockets with this bulb,
and some don't. My electrically inclined friend explained that this
could be caused by a loose or dirty connection at the socket, which
causes the socket to act as a resistor, creating additional heat.
So I used dielectric grease liberally on the connectors to avoid
this. I bought the bakelight high-temp socket from Napa (see the
FAQ for p/n) just in case. Could I remove the wires from the OEM
socket with the connectors intact and just insert them into the
bakelight socket, so that I wouldn't have to cut the OEM wires?
The extra light is easily noticable. This upgrade was quick, easy,
cheap, and adds zero extra weight.
Any comments appreciated,
Eric

I've been running that same 80/100 NAPA job since the spring with a
15A fuse and the stock connector. No problems with melting the
connector or blowing the upgraded fuse. I do at least half of my
driving at night(the benefit of a midnight shift aircraft maintenance
job) switching between hi and low beam as the 100W is pretty blinding.
During the day I just leave it on hi. Good light although I can't run
my aux lights(2 55W mini's) along with the headlight. Too much draw
for my weak stock stator. If there was a quality high output stator I
would certainly consider it however I keep reading bad reviews on the
high output units that are currently available. Short lifespan I hear.
I think you've got the best setup you're going to find.
Good luck.

It may be possible. You need a tool to remove the connectors
from the sockets. Various sized paper clips will work with
patience. Mark from Marknet KLR650 tried it and didn't like
the fit. I have done it many times with different connectors
but never this particular combo. You may get satisfactory
results by tweaking the tabs.

Eric,
On the surface it sounds like you found an easy way to get some better
light. If you dig deeper I don't know that that will really be the case
with how you've done the job.
I think the extra load, either low or high beam in operation, will push
the limits of the stock wiring and switch contacts. I've heard multiple
times on this list about people putting a 15 amp fuse in to replace the
stock 10 amp fuse. If the system is working correctly and you are making
decisive switching between high and low beam the 10 amp fuse should be
just fine. If you are slow on the switch and hang up with both beams lit
I think that's what blows the stock 10 amp fuse. I've never put a 15 amp
load on the stock wiring to see how it reacts but I bet it get darn hot.
Fuses are put into a system to protect everything downstream from the
fuse. The stock wiring isn't very heavy and the switch contacts on many
bikes are also kind of light. I suppose but don't know for sure that the
KLR also has fairly light switch contacts. Asking the wiring and switch
contacts to handle an extra load in my opinion is asking for trouble.
Adding a larger fuse is just begging to burn some wires and let the smoke
out. Your system worked fine with the 10 amp fuse. Why not continue to
use a 10 amp fuse until you have a problem with it blowing? Then examine
your wiring before you install the 15 amp fuse.
I think if I wanted to run an 80/100 watt light I'd add new fused wiring,
relays and the NAPA connector. And the relays would be controlled by the
stock low and high beam wiring. That would put almost no load on the
switch contacts. And if you do a good wiring job with large enough wire
using relays you should have virtually no voltage drop at the headlight.
I think your friend explained it pretty good with the loose connector
acting like a resistor. Maybe your friend could help you do a voltage
drop test at the head light (positive and negative sides) to see how your
wiring is doing. I bet you have over a 1 volt drop with the stock
wiring.
Best,

> What was her family name?
I don't know but maybe someone on the list does. She didn't die
when the fish taco truck hit her though as has been reported. I
found her picture on the DSN KLR650 members photo site. She is
living in Taconite MN. still likes fish and has a chopper.
