This is the first of the BCCCB LED Experiments. There are plenty of products out there claiming to be superior to the old products we use. In this experiment I am trying to determine if LED tail lights / brake lights are worth the money and to see of they are safer then the old conventional lights. Lets see shall we.

 

Above you see the differences between the old lights and the new LED lights. By 1879, Edison had produced a new concept: a high resistance lamp in a very high vacuum, which would burn for hundreds of hours. While the earlier inventors had produced electric lighting in laboratory conditions, dating back to a demonstration of a glowing wire by Alessandro Volta in 1800. So, the concept of the original lights in your car are basically a 100 + year old concept. Light emitting diodes, or LED as we call it are the new kid on the block. Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material. Wow! Imagine using a semiconductor in al old British car, surely those who built these beauties would scoff at such a thing. Lets proceed shall we.

  

The replacement of the old conventional bulls is simple, remove the lens and push and turn the bulb. Now with fingers as big as mine, getting a grip on the bulb was a tad difficult as the bulb comes close to the reflector that surrounds it but with a flick of a screwdriver it was in my hand. These bulls are what is called an 1157 which are duel filament bulbs, one filament for the park lights and the other for the brake light. Pressing the brakes lights up the second filament creating a brighter bulb, The replacement LED bulb is an 1157 type as well. The 1157 bulb has locater pins that are not aligned so there is only one way for them to go into the socket. Looking into the socket you will see that one groove is deeper then the other so press in the bulb with the prong closest to the bottom of the light into this groove in the socket a quick twist and your done. Turn on your lights and have a look. I should, and am suggesting that you take a few moments to shine up the reflector as mine were a tad tarnished, a little shining may have enhanced the light output.

Lens on, park lights on, now have a look and draw your own conclusions. I like the results of the park lights. I like the new light pattern and as you can see it's a brighter and fuller light. We may be on to something here. Now.... these LED lights are an eBay purchase, a mere $16.38 shipping included for 8 bulbs. Barc had paid a few dollars more for his but there is a difference. My lights have 36 LEDs and Barc\s have about 46 LEDs so I am sure there is a difference. Thus, this experiment is incomplete at the moment. OK the park light experiment looks good, lets check out the brake light test.

I had to get the BCCCB Princess (Paula) to press the brake pedal for the second part of this experiment ( The pedal in the center? She asked). The results at this point were a tad disappointing. Again, I do like the lighting pattern but I find that the old conventional bulb to be brighter. The idea behind this experiment is to brighten the rear bulbs for no other reason then safety so personally, I prefer a brighter brake light over a brighter park light, so for me... at this point anyway, the experiment is a failure. I would like to try Barc's 46 LED lights to compare. Also these bulbs are red and maybe clear would produce a brighter light. So, once again this experiment is still ongoing and I will post all updates as this experiment progress. I hope this helped with your LED debate and decisions.
