If you really need LED lights in your car :
Buy some LED Christmas lights and decorate the inside of your car. Just plug then into the cigar lighter inverter.....
thats what the hippies do around here........ |

You bring clear technical analysis and a wealth of knowledge and information to the debates and evaluation of lighting products. You catch a great deal of crap from many people for giving brusque and sometimes biting commentary, but such comments are really not deserved. Your comments shine the cold light of logic and science through the murk of profiteering and the haze of advertising. Critiques like yours are necessary and invaluable, and you do it all for free. And you keep doing it after getting repeatedly insulted.
I salute your dedication to helping other and the depth of your knowledge. You really are a great resource and we should all be very happy you take the time to save us from making horrible mistakes that have a strong possibility of killing us. Thank you. |
I would like to second this and say Thank you Dan for sharing your knowledge with us.
Dave

WHOAH. Wrong way to do it, bigtime.

Yeah, you do, you just don't realize it. It sounds like you care at least a little, which puts you head and shoulders above the goofs who think their car's lights are toys rather than life safety equipment.
"Visibility" means way, way more than just "Do they light up real bright?". It is not impossible to make your own LED car lights and come up with something adequately safe for use in public-roadway traffic, but it is a great deal more difficult than most people realize. See threads here and here for two examples of homemade LED light projects with the right amount of thought, effort, understanding, and technique behind them to be probably safe. Seriously, everyone reading this thread ought to go read those threads. Even if you don't care a whit for the technical stuff, the amount of craftsmanship that went into the mods is a beautiful thing to see. |
WHOOOHOOO!!!  I just got linked. Thanks SlantsixDan. I enjoy doing upgrades on the dart and didn't expect to get it linked and yeah safety is a factor in the upgrade. of course the first time doing it on my own with out numbers or a way to check the light made me fail miserably and we ARE NOT talking about how bad I did on the front ones either  (everything was way to bright and I couldn't get the ratios correct) the original (LED full tail version) tails measured in at about 200 candella and 600plus on the brakes.I kept upping the MA rating for the brakes instead of lowering the tail function,after I figured out that I was reading a borrowed light meter in the wrong setting/scale or some such setting and SSDan sent me the values that I needed to look for I corrected it, they were really (BAD)HURT me bright as in you couldn't look at them for more that a few seconds in tails and hardly at all on brakes and it DID leave spots in your eyes for a while afterwards.
the C ring section that I did later was right on the money, numbers, ratios and had good conspicuity (hey learned a more about a word!!) and yeah I had to look it up I thought it just meant obvious ahhh! but it was more, sort of like a punk rocker doing his/her hair in bright green and orange colors. sort of makes you have to notice him/her. which is what I want the lights to do and not hurt you.
I am redoing the original full lighted version for correct ratios and candela
ratings so that I have a choice of stock appearing (sort of) and the later C ring version
again thanks slantsixDan for your help in getting me close to or at the settings and safety I need for the dart.
