When I turn on my high-bright I want both bulbs to light. Any suggestions and/or issues on how to achieve this? I have a 2005 A

Simple to do. On the left hand control, make a jumper between the yellow and blue wire. It is easy to do on the grey 6 pin connector under your left side cover.

Is that configuration street legal? Or will you have to reverse that to pass a state inspection.
On my Subaru, when you hit the high beam, both the HIGH and LOW beam lamps are lit.

I *think* it's okay, as long as you don't have fog lights on at the same time.

I can think of a possible problem if you run this dual headlamp setup:

According to published information the output rating for the VRSC alternator (regulator controlled) is 36 amps. That's 522 W @ 14.4 VDC (also controlled by the regulator).

If you add up the various loads on the alternator (this is a worst case situation):
1) low beam, rated 55 W @ 12.8 V or 70.58 W @ 14.5 V
2) high beam, rated 65.3 W @ 12.8 V or 83.8 W @ 14.5 V
3) tail lamp, rated 8.3 W @ 14 V or 8.9 W @ 14.5 V
4) stop lamp, rated 28.8 W @ 12.8 V or 36.96 W @ 14.5 V
5) frt.running lamps, rated 8.3 W @ 14 V or 8.9 W @ 14.5 V (X2)
6) four-way flashers, rated 28.8 W @ 12.8 V or 36.96 W @ 14.5 V (X4)
7) license lamps, rated 4.6 W @ 14 V or 4.93 W @ 14.5 V (X2)
8) ECM/TSSM/misc, 1 W @ 14.5 V (approx)
9) radiator fans, 85 w @ 14.5 V (X2)
total power requirement: approximately 547 W

This exceeds the available power by about 25 W. I know it's unlikely to need all these things at once but it is possible and running both headlamps doesn't help.

So just remember that if you pull off to the side of the road, and put your hazzard flashers on, drop to low beam....

Will this allow the low beam to be on by itself, i.e. high beam off, when the switch is set to the low beam position?

Yes.

Essentially, you are wiring the Low Beam all by itself to be always on.

Therefore, if you flip the Hi/Lo switch, then you will only be operating the high beam. When you put it on the lo position, it just turns off the high beam. (The low beam is hardwired on all the time.)

I have the new HD LED Tail/Stop Light as well as aftermarket LED signals. Wouldn't that provide a reduced draw and a greater buffer?

devlpr,
How do you like your HD LED tail/stop? I assume you mean the rear turn signal mod into stop/tail/turn.

Love it! Would definately suggest putting it on your list!

Rear and front.

Yes. Significantly so, if you use LED TURN SIGNALS, AND an LED TAIL LIGHT.

Sounds like a great excuse to buy a Heavycycles light!

The LED taillight, as you said, is a significant benefit but I'm not real sure about the benefits of LED turn signals. What's the load of the required load equalizer? Regardless the signals are intermittent so there not as much of a concern.

I know the Accesory circuit only pulls 350 milliamps or so while running. 450 milliamps with the stop light on. I measured these closely while working up specs for the Keyless Mod. Both mine, and Ruthann's are running LED's on front and rear turn signals. This includes a Smart equilizer with the setup.

Other than the lower amp draw, the LED inserts (The ones from Heavycycles) are brighter.

If anyone has a photo of this circuit board and the "jump" made that would be great!
