Are you using incandescent / filament headlight bulbs Bill?

Fog lights recommended in that mess.

Post a pic, instead of a link. Are you posting from a phone ? Get on a laptop if you are.

Yes, I'm using the standard halogen Sylvania Bulbs. I wish I could post dash cam footage of the light pattern in San Francisco's fog. Uplifting and more like a Lexus headlamp than a 20+ yo truck.

I'm using the Sylvania halogen zXe bulbs and am THRILLED with them. Brightest I have seen without doing an LED/HID conversion.

I also just ordered the 800 lumens back up lights from Diode Dynamics. The LEDs I already have in there are 250 lumens and they light the neighbor garage up. I can't WAIT to get the 800s!!! There is no direct link, but note there are 3 bulbs options for the WJ on the page linked below. I found these guys in the WK forum (I think). Promotion code BF21 for 15% off.....

@Mr. Bitey ,
It would be interesting to measure the current draw of that LED lamps; I wonder if all those leds draw more or less current than the standard incandescent bulbs.
I think that all this current flows in the contacts in the Solenoid Block assembly in the transmission (but I am not completely sure), and an increased current draw from lamps is not such a good thing. But probably I am wrong.

A very interesting point Mak.
80 lumens per Watt seems a popular opinion.
850 lumens - 11 Watts.

Brake light bulb 21 Watts.

I add a new discussion point: usually LED lights have (should have) a current draw lower than the incandescent lights (of course considering same light power), but how about the peak current when lighting up?

Is the lighting up peak current of a LED lamp (let's remember that led emitters have a circuit that drives them) less than the incandescent lamp?

When the filament is cold it's resistance is lower, much lower, than it's resistance when white hot
I'm sorry, don't have any figures handy,

If you complete a circuit through an incandescent bulb by flicking a wire across a bulb contact you will get a spark.
The spark shows a high current through the cold incandescent bulb.

If you complete a circuit through led bulb by flicking a wire across a bulb contact you don't get a spark.
The lack of spark shows there is only a small current through the cold LED bulb.

This would indeed be interesting to note, mak. I probably will not do it merely in the name of science, but I will conduct your experiment if I have to replace another bulb. However I would bet the draw is less than the OEM incandescent bulb despite it being much brighter.

Side note: The 800 lumens Diode Dynamics bulb is not much brighter than the 250 it replaced. At $90 for the pair, I am not real thrilled. Of course since I have no way of measuring lumens, the 800 and 250 are just arbitrary numbers therefore my eye is the only gauge.

You win your bet hands down Mr B

Do you remember when you drove with a dead headlight bulb, it didn't make that much difference did it?
It's not only that your eyes aren't good gauges, it's down to needing to quadruple the the lumens to get twice the distance.

If you find a road with white or reflective posts at equal distances, you could count the number of posts you see on a dark night with 250 lumen bulbs, them 800 lumen bulbs.

From memory, the light per post / reflector falls by the square of the distance from the source.

So, if you can count 10 posts with the 250 bulbs, and 20 posts with the 800 bulbs then the 800s are 4 times as bright at the 250 bulbs.
I think 17 posts would be about right for the 800 bulb

My 800 lumens comments was in reference to replacement backup lights as noted above, not headlights. The zXe headlights I referenced above are closer to 1500 lumens, and I have no complains about those. I also wouldn't call counting posts on the side of the road a gauge of accuracy any more than my own eyes as I doubt any of us know what X number of lumens actually looks like. Since none of us have a lumens-o-meter in our tool chest, outside of a lab it is an arbitrary number. I often find your posts quite cryptic, casting confusion on what is already understood and rarely understand your point.

Thanks Mr B & thanks WJ.

If you have any questions about things you don't understand I'll be happy to answer them.
