XJR1300 Alternator

[Mattman]

Hi Fred,

Where can I get a pair of clear running lights for my 93?

The lights are as follows.

Turn signal/running lights...White 5000k/Amber Cree Switchback LED 60 watts

Headlight...5000k HID 35 watts

Auxiliary driving lights...5000k Cree LED 120 watts/3000 Lumens

I will be able to get actual running amp draw numbers later this evening.

No, Fred has many more mods of his FJ than I have on mine...

....then again, I can only think of one 1350cc FJ (in the world) that has an uber trick 24v starting system...

Shhhhh .... The 1st rule of 24V starters ..don't talk about 24V starters!

    Hey Fred,
  If we assume that the signals are 2 x 60 and the running lights are both 120 and the headlight only35 (?) without
a taillight that is nearly 300 watts total. That will be well over 20A total. The ignition system might  be good for an
additional 5A. An amp or so to keep the battery happy, , , hmm, , how much amperage did you say that FJR alternator
is designed to deliver?  The lights in the pic look like they're getting plenty of power. I guess we'll see when you put an ammeter in series with that load. Careful doing that, if your Fluke is like mine it has a  fast fry 10 amp expensive/i]
fuse in it.

I just dug up an owners manual for the XJR.  The alternator specs out as 28A@5,000 rpm. About the same FJ, IIRC.

I was not able to get any amp readings last evening. I will get the readings this evening. I know about the Fluke fuses. I have 3 Fluke meters. An 87 V, 179 and a 375 clamp meter

Here are the actual lights that I have.

Turn signal bulbs....http://www.ebay.com/itm/2X-1157-7528-Cree-60W-Led-Amber-White-Switchback-Turn-Signal-Light-Projector-/371374555871?hash=item5677a602df:g:HfgAAOSw9N1VmeY3&vxp=mtr

Auxiliary driving lights....http://www.ebay.com/itm/2x-125W-CREE-U5-LED-Headlight-Driving-Fog-Spot-Light-Lamp-For-Motorcycle-Switch-/112175611116?hash=item1a1e2ffcec:g:kxgAAOSwUEVYCh5X&vxp=mtr

I am not going to list the HID headlight, being as they are typically known to draw 35watts.

To help keep the power draw down, I do have a LED tail light installed.

Fred, this looks like A LOT of lighting.  However, lighting is like both speed & horsepower;  too much is ALMOST enough!  That being said, I have 2 questions:
1.)  How many amps do the 1157 signal-running lights actually draw? 
2.)  How well does the white light pass through yellow lenses?  I like the look of the yellow lenses, and would rather not change them, even with amber flashers.  If you still have the OEM lenses perhaps you could pop them on & do bit of testing. If not, c'est la vie ...
Thanks!

That is an awesome quote.


I will be getting the amp draw on all of the lighting shortly. I think I ha e a stock set of orange lenses I can pop on for experimentation purposes.

Here is the answer to your questions with the Cree switchback 1157 bulbs.

1. The amp draw with the white running lights is .4 amps.

2. The white running lights have a good bright glow through the orange lenses and the orange light gives a good bright glow, just a bit of a darker shade. Photos are as follows.

1. Running light with the orange lens.

2. Turn signal activated and the flash off.

3. Turn signal activated and the flash on.

An added benefit that I like that IMO adds a bit of better safety factor is that with the switchback bulbs. When the flash is off, there is actually no light illuminated. With the OEM style incandescent bulbs. The running light alternates between the running light and brighter turn signal filaments.

I was able to get amp draw readings from all of the running lights.

HID headlight=3.2
LED Running lights=0.4x2
LED Auxiliary lights=0.4x2
LED Tail light=0.3

Total amp draw for all of the lights at 2500RPM is 5.1 amps

I used a Fluke 375 clamp meter

Thanks for the information Fred.  I think you slipped a decimal place on aux lights though; 0.4 instead of 0.04?
Q: are the signals brighter than the running lights?  Otherwise, I like everything I see. I agree that the on-off when flasher is on is a cool deal. Surely more conspicuous FWIW.  'They' - cagers-- seem to ignore them anyway.

[aviationfred]

Good catch Ed. You are correct, I fixed it.

The White and the orange LED's have the same light intensity. They are extremely bright. The lenses diffuse the light quite a bit. At night, or even at dusk. I have noticed that when the turn signal is turned off and the white light comes back on. More road area lights up on that side. Kind of like the Cadillacs did back in the '90's and early '00's with the white bumper side lights that came on whenever the turn signal was activated.

Great posts, Fred and Ed. The LED lights use a lot less power to produce the same light. I just bought some LED light bulbs for around the house, these light bulbs produce 60W of light and only use 9W energy.

Fred, I thought of a few more things:
1.)  What happened with the flash  rate with the LED turn signal bulbs?  Same? 
2.)  Did you add resistors to slow the flash rate? 
3.)  Does your self-cancelling function still work?

Sorry, inquiring minds want to know.
Thanks!
