Yes, they are 42 Draft Designs BAX9s. Working great for me so far. I replaced them because the old halogen (city lights) were burning out every couple of months. Will let you know if these do too, but I doubt it.

Im have 9005 LED bulbs (Ebay) used as full voltage DRLs. Last week in California (Fresno), 90-100F, they both seemed to cycle on and off independently at a somewhat regular basis/period.

Supposedly they have an internal "active" constant current ciruit source that allows them to operate, and maintain the same bright level, from 12 to 24 volts.

Anyone know..?

Does the constant current source also provide thermal protection?

Those look like some well built LEDs..not cheap comparatively but if they work well, maybe worth the upgrade

I forgot what I used but I replaced them with LEDs I ordered from a VW specialist. Did that maybe 3-4 years ago and they're still working.

There is no need for "50W" LED for this application, these are supposed to be "city lights" to consume a small amount of energy while parked at night so other drivers can see your parked car on the side of the street. 50W is overkill and will drain your battery quicker if you actually use them with engine turned off.

I also have a hard time believe the individual LED chips are 5W each, I think they are playing with words that the power consumption with the current limiting resistor is 5W each, not that the LED chip itself actually consumes 5W, else it would be either a very inefficient LED, or an ubber ultra bright LED that would cost much, much more, or overheats in no time!

As well, at least on my car, these lights come on when my main headlights are on, they are completely overpowered by the HID headlights, serving no purpose at that point, no idea why Porsche wired them in such manner.

These ones http://www.ebay.com/itm/2pcs-BAX9S-H...8759c0&vxp=mtr will more than do the job for much less cost.

Power consumption = 2 x 3W.....

The factory intent for the H6W bulbs mounted in the headlamp ***'y is for use as actual DRLs, not street/parking lights. H6W or appropriate LED makes use of the high beam reflector for distance visibility not just a single forward projector LED.

DRLs, H6W bulb was developed specifically for DRLs in europe.

Look carefully at the base.

I don't have anything on hand at the moment to counter your comments that H6W are used as DRL in Europe.

However, realistically the 6 watts (as confirmed here http://en.wikipedia.org/wiki/List_of...ght_bulb_types) incandescent H6W bulbs that came standard with the car can only produce a very small amount of light that surely can only be very visible at night, how is that going to be effective as a DRL when the DRL on modern (non LED DRL) cars are often the high beam bulbs running at reduced voltage (or duty-cycle), so at half the voltage (or duty-cycle) the high beams bulbs are still run at close to 30 watts, far brighter than the 6 watts H6W bulbs can achieve.

Unless daylight in Europe is much closer to night time in North America.

Can any US owners confirm your US cars actually use the H6W as DRLs? i.e. do they turn on either automatically or when the handbrake is lowered after engine start?

On my 2000 Canadian car, the pair of HID headlights come on full strength as soon as I start the car and remain on regardless of ambient lighting level until I turn off the engine, i.e. the HID headlights in my car ARE the DRL, and very bright, which then completely overpower the little incandescent H6W bulbs whenever the engine is running.

Pulling and turning the headlight switch counter-clockwise to the two positions from the off position also individually turn on the left or right sides city lights, front side marker lights, and rear tail lights on the side selected.

No, these are only on when you turn on the parking lights. Not full time.

WWest - can you get a picture of what these look like when on. A shot of the car facing a wall would be helpful to see how much light is actually broadcast

wwest, is your car from Canada by chance? I know on some non-Porsche models for example, the Canadian cars came with the DRL option programmed from the factory. This could be one of those options that can be activated or deactivated via PIWIS or PST2.

Either way DRL = Cop Magnet for me so no can do and no care.

Having lived and driven in Europe I can absolutely assure you H6W is not used as a DRL in Europe. They are parking / city lights.

DRL are 24W bulbs - typically PY24W.

Aviography: Have you actually been using those? I would be interested but I'm worried about LED longevity in a hot HID environment.

Not these ones specifically, but same ones with the wrong base with the two little pips 180 deg apart rather than 150 deg apart of the H6W in our cars, they were US$3 a pair shipped to me in Toronto, so I bought two pairs with second pair as back up.

So far all 4 units work, the head section of one unit is loose which then turns continuously when trying to install into the socket, but the light itself still works which I found strange.

The vendor is going to replace this unit for me, the pair in the car has had about 10 hours of run time and are just fine so far.

For the low price, I don't really mind even if they burn out because they don't really serve any real purpose in North America! And I don't think the heat build up is very high anyway within the huge volume inside the headlight housing.
