Just installed my LED brake lights from Clear Alternatives. I kept my stock red lens. I did a voltmeter check before and after, which may interest some of you. Here's what I did:
I took a voltmeter reading at 3 settings before and after the install, each time with and without the brake pedal depressed. The 3 settings were as follows:
1. key on, engine off
2. while idling at 1050 RPMs, after warm-up
3. at 3000 RPMs
The results were as follows:
...............................idle @
...................key.......1050........3000
...................on.........rpm ........rpm
bulbs tail....12.42.......13.70.......14.14
bulbs brake 12.29.......12.82.......13.50
volts drawn. 0.13.........0.88.........0.64
LED tail......12.45.......14.02.......14.18
LED brake...12.41.......13.82.......13.85
volts drawn. 0.04.........0.20.........0.33
These reading confirm that the LEDs draw less power both in the tail light mode and in the brake light mode. Compare tail light to tail light (bulb vs. LED) and brake light to brake light (bulb vs. LED) and the volts drawn when applying the brake lights (bulb vs. LED) and in all categories the LEDs are have higher voltmeter readings and less draw when using the brake lights. The differences are not linear, probably because of the particulars of my battery condition, R/R and stator. But I'm convinced that using LED brake lights are a savings on my electrical system AND seem much brighter from the rear. From the side view, the LEDs are about as bright as the bulbs were. I'm happy. Thanks all for your help with this decision.
