Long lasting filaments have a higher resistance and less light output.

I'm not too sure of what I say, maybe you can enlighten me.

What we need is Sparkie, he knows what wires will turn him into smoke.

Enlighten you? On Ohm's law for power in a DC circuit when voltage and resistance is known? Naw nothing to 'enlighten' you about there. What you should be doing is taking the Ohm's law for DC circuits for finding the UNKNOWN (resistance) and applying it to filaments that exist for automotive bulb use. Lets see, as a reference only (as system voltage varies with load and supply) lets use 12.5v at 100 watt output, we come up with approx 1.56 ohms. Now lets find out how much a filament would cost in this application in the gaseous environment necessary to not blow out with any reasonable time span. I don't think there is a known filament with this specification, but if someone who has these elcheapo bulbs would take a quality DVOM and report back here the bulbs resistance, we'll see how much actual power in watts these bulbs produce at the specified voltages applied.

I ordered a pair out of curiosity, I'll OHM one when they arrive and let you know .....
( I'll also measure the OEM bulb )

I live but to serve ........ ( as I understand it, service earns you citizenship, right ? )

George, we seem to like a few things in common huh... I think you were saying the regular filament bulbs right? The LED sets are semiconductors, they will not follow the simple ohm's law for D/C circuits rules. Do you want to know more?

yep, the magical Chinese bulbs that double the light output without drawing any additional amperage.
( BTW: you caught that reference correctly, Starship Troopers )

try this one :
These Chinese bulbs only come out at night, mostly ...

I have been following this thread sporadically. What is the consensus here, are these too bright for the license plate lights or not? Are there more than one brand/style that you guys have used?

They are very bright, i keep the origionals in the trunk so if i get pulled over i can swith them out to avoid a ticket.

I just tried to make some photo's with my phone but u can't see much on it, i can upload it if u want.

Dont think its no where near that bright. most new high end MBs the lexus, nissans etc come with these from the factory. So this is an update, all these incandescent bulbs will be a thing of the past soon.. the Crossfire is almost a fossil by now at least mine, a build date of 03

Sorry for the poor quality, but there pretty bright.

I bought them from this link:

http://www.ebay.com/itm/130688521236...L:3160&vxp=mtr

Free shipping, it took 13 days to arrive from hongkong

They look great! Been rolling with them for just about two years without a problem

Is it just me, or are mine not "clicking" or "snapping" in place? From the look of it, one clip goes under the metal, and the other is held in by tension. Sound right?

Also, for anyone wanting to further their LED conversion, I just listed a pair of 48 SMD red LEDs for the tail/brake lights. Accidentally ordered two pair. They look great in my car and are so much brighter than stock halogens. Check it out and PM me!

And just another idea of how these look with LED tail lamps.

I'm local, what did they cost new?

If you don't pick them up for some reason let me know and I can take them off Smokey's hands.

Go ahead and snap them up.

Smokey, can you post the model number of the lights for future reference?

Thanks,

Thanks,
I went to the manual and grabbed all the part numbers for all of our lights, and when I went to that website mentioned they didnt have all of them. I ended up typing in the year make and model and it came up with a bunch of bulbs for us. I think Im going to convert everything I can to LED, I havent done anything yet.
