I forgot where I found this, but this is exactly the same device you can build yourself for less then $10.
Chris, I built one using these parts and it works great plus you can use the volume control to dim the LED's at night.

I used the 1551GBK plastic enclosure or you can use a bigger size box which I placed 4 1.7v 3000mcd LED's from RadioShack part number 276-307.
Make sure when wiring up you get the polarity right, I had a coiled cord lying around with a 3.5mm plug on it so I used that.
After I soldered everything up in the box used some black silicone to fill the gaps in.
Glued a piece of black plastic on the cover to get the angle that I wanted, added some velcroe to the box and the screen on the bike and that was all to it.
I wired the LED's parallel and did not use any resistors as I did not know what voltage comes through the earjack outlet on the Escort.
Regarding polarity the longer leg on the LED's is positive and the centre tip of the plug is postive, if you wire up the LED's polarity wrong to the plug the unit will not work.
Had a chance to compare my unit against a VA and they both light up at the same time and the VA looked a bit brighter but my unit is bright enough and adding a resistor you could increase the brightness if so desired but mine works great, the angle of the LED,s to your eyes is important as the viewing angle of the LED's is only 12 degrees.
During the day have volume control of the Escort up to max and night time adjust the volume control to dim the LED's otherwise you will be blinded [/QUOTE]
