I've decided to upgrade to LED headlight bulbs on the 06' VFR.
I have H4 LEDs rated 3000lm low, 3600lm high. Both of which are cooled by fan and heat sync.
Now, on the Honda we all know that the H4 only uses the low-beam, and then it uses the H7 on the high-beam. I've seen the attached diagram used to hard-wire both Low and High to work simultaneously on the H4, along with running the H7. So, in theory, you'd have 6 filaments running at once on high-beam, and 2 on low-beam.
Honestly, having the amount of Lumens that these bulbs do... I only need to be running an H4 in each bucket hi/lo and have no use for the H7. Plus, I don't want to be completely illegal / obnoxious with that much light coming from the front of my bike.
I have 2 different ideas.
-Leave the stock wiring in-place, and the stock relays.
1. Unwrap both High and Low beam leads.
2. Remove power lead from the H7 connector.
3. Place it into the open clip on the H4 connector.
At this point, the High/Low will operate on 1 bulb, with 1 connector, using the OEM harness and relays and you will have an un-used ground left on the H7 harness which can be plugged back into the H7 and left alone.
OR-
Do steps 1 through 3 above.
4. Splice the low-beam power lead and run a jumper from it, to the H7 connector where the old high beam lead was removed.
5. Install a low-wattage, low-lumen H7 LED as a "running light" (can be white or amber in most states).
At this point, your High/Low will operate on 1 bulb, with the 1 connector, using OEM harness and relays and you will have a running lamp in the old high-beam slot which will be on at all times.
-----------
I figure LED's run a lot cooler, and draw a lot less than a standard halogen, so it shouldn't damage the harness or housing in any way, and might prevent future damage to the R/R buy lowering over-all draw.
The one thing I want to figure out is... if I run a 5 pin relay and run the low-beam through it (like in the picture)... can I get it so that the low beam and running lights are on all the time, and then when I hit high-beam it's JUST the high-beam on...
If I can figure out how to get that to work, I may put an in-line switch to the driving lights... that way they can be controlled by a switch as a "fog light" and will kick off automatically when the high-beam is turned on.
This setup will be the most "legal"... Lows on all the time, driving light optional, and high beam is ONLY the high-beam when turned on. (Plus, I can run yellow H7's as driving lights, which is what I do on my car in the fog lights.)
Thoughts?
