LED lights round #2!

I don't know why I do this to myself. I can't leave well enough alone. Plus a part of me thinks LED interior lights are going to safe the earth or something. Wayyyyyyyyy off! I found a different vendor that has LED lights with a BUILT IN voltage limiting resistor.

So, I spent another $90.00 on 8 LED bulbs in hope they hold up. If they do not work, I will write off the LED light idea. I mean, I don't even want to break out a calculator to find out the ROI on this project!

Aaron, did you just replace the interior (I'm asssuming 8 LEDs means you changed out some exterior as well or did you mess with the gauge cluster)?

I purchased some bulbs from Hoen high performance halogen for my high beams, fogs, and license plate lights since these bulbs match very close to my factory HIDs and the license plate bulbs are the nice bright white, without causing the indicator light to go on. Not as crisp as the LEDs but much better than OEM.

There's nothing worse than running exterior LEDs and having the dreaded spazz flash when one of them goes bad (which I fell victim to on more than one occasion).

Can you link us up with the new LED company with built in resistors? I may wait a while to let you see the long term results, but not having to wire up a resistor myself may be worth trying out these new LEDs.

The proper way to do this would be to use an integrated LED driver. There are drivers available that will maintain the desired current through the LED (important for both brightness and color temperature), compensate for temperature, protect against voltage spikes and reverse voltage, and tolerate supply voltage variations. Here is an example: Allegro | Product | A6260 High Brightness LED Current Regulator
One or more of these driver chips could be incorporated into a filament bulb replacement. I don't know if any supplier does this, but if I were in the market, I would ask.

Replaced license plates lights (2), interior dome (2), trunk area (1) and glove box (1). Plus a couple as spares. I don't want to endorse anything yet, but SUPER BRIGHT LEDS home is where I am getting them from. They will arrive Thurseday.

DickB,

Totally off subject but I wanted to tell you about the MP3 adapter.

You know how I thought increasing the ampflication level would be great for mp3 player battery level? One problem I found out. MP3 players like all amps have a effiencey level. If you drop the sound enough, the THD level of the mp3 player goes up ALLOT. So yes, you can amp it more, but the increased distortion level negates doing so. Sorry to have questioned you!

All the best,
Aaron Lephart

I agree with you, papa. What's the point in dicking around with perfectly good normal lights?

Anyway, to do so with exterior lights is illegal in the UK, as far as I'm aware. No 'E-mark'!

So replacing a bulb that is burned out is illegal in the UK too?

A real benefit of LED brake lights is that they turn on a few milliseconds sooner than filament bulbs. At 70 MPH, that can amount to perhaps enough distance to prevent getting rear ended. Of course, the SLK third brake light is LED.
