  • Helpful info about LED lighting

    Hey all, I ran across this thread as I was browsing www.termpro.com , a car audio site I frequent. This thread has some useful info dealing with using LED's for interior lighting in a car. I've seen some of your installs where the mobo is highlighted with LED's, and i figured this info could be useful. It deals with the diffrences between brightness, MCD's, and intensity to help you choose the right # and type of LED's to use. Hope this is of use.

    I'll head over and check it out. I have done some major reading on the LED usage and legality on the exterior lights in the past. I still wonder why we can't use white LEDs with Extra high lumens as our headlights. They could be brighter and whiter than the new HIDs. No heat either.

          [AUS] I thought you might want to know that jaycar, have little pcb's, for turning your stop/tail/turn and interior lights to little LED lights. Apparently (So i have read in an AD) The LED's are brighter and because they illuminate instantly when stopping from 100km/h they can shorten stopping distance by up to 5 meters. I was like wow. I am keen to give it a go, next time one of my globes blow i will try it myself.

            My SVX has LEDs that I replaced. Not the cheap 10 bucks ones you get from autostores but a huge matrix of LEDs on each stop light at the back. All I can say is that they make a huge difference between stock lamps since those take a while to light up compare to LEDs. Also, LEDs are a lot brighter as well. With all 4 LEDs on, I can light up a whole city block. The they are fully street legal since they came out of a truck tail lamps. The whole set of LEDs set me back about 150 bucks but it's well worth the price.

              I've put those Luxeon Stars in my rear turn signals, 4 per lamp. It was plenty. But they surely generate some heat at 1W a piece.

                Yes the thing about LED's not generating heat is certainly not correct. They run cooler at the same lumen output as an equivalent incandescent, but they actually run quite a bit hotter at the same power levels.. Ie a 5W light bulb does not get as hot as a 5W Luxeon STAR. Yowch.

                Finally some good info is coming out on retrofitting BMW's OEM LED tail lights into older BMW's.. This is probably a modification that I will do sometime soon. They are really slick but at ~$500 for the upgrade it's a bit pricey..

                  I have a hobby of making LED lights, dont want to post the site as I dont know what the rules are on that stuff, but luxeons are what some consider a step design. in that they are not finished, or shouldnt be. they are horribly over priced and dont really offer much over a normal LED in terms of design. a 5mm LED uses a tiny die that creates basicly no heat. luxeon just magnified that die, thus more light, more heat.

                  I still use luxeons however... as they are the only one to put out that much light. can do some crazy stuff with them.

                  that BMW price is actually extremely reasonable. the G35coupe tails are 2grand, and Im unsure if thats a pair or each, I beleive its each, but that just seemed more unbeleivable. 500$... Id double check that, as a normal tail light housing costs that much, ignoring the hundreds in LEDs that are in each one.

                    i used pre-maid modules for trucks and installed those. The only one i had to make was the reverse since white LED's are still expensive, the only modules that i found where about $150-200/pair. The amber and red modules cost me about $20/each.

                    if you look on page 5&6 you can see the front turn signals i made as well.

                      hey, thats pretty clever, wont work for all cars, but fits nicely in the maxima.

                      that is pricey, but if it works, why not.

                        A cheap source for drop-in LED bulbs is superbrightleds.com. I built these into my MAME cabinet to illuminate the control panel but found the white 6 led wedge base bulbs to be a good match to the xenon lights and bright enough for use in the interior, so I'm going to order some more. They have some pretty large array bulbs for use in turn signals, etc. als, though you might need a load resistor if your car has idiot lights to tell you that your bulbs are burned out...

                        I did check to be sure on the BMW E46 LED Taillight retrofit. It's indeed $500-$700 depending on what the dealership charges to program your LCM and whether or not you need a new LCM entirely... The actual taillights are suprisingly not very expensive!.. They uses rings of Luxeon 1W led's in them. There is a kit for $60 to activate the "Adaptive Braking" feature that brightens the lights when you stop harder that is not available in the standard retrofit.

                        Here is the source of the info

                          maybe Im missing it, are you guys upgrading to the 04 style tail lights entirely(matrix of LEDs in a totally different housing). or just modifying your tails to house a ring of LEDs(guessing the 6luxeon ring).

                          I thought you were talking about the former, but the price and explanation on the site sounds like the latter.

                          cool idea to incorporate all the other stuff with it though.

                          Im working on a 7443 bulb that uses luxeons, I only intend to use 4 for space issues, but itll be nice that it fits with no modification. 4 in the right direction can do alot.

                            Yes the E46 LED retrofit for $500-$700 replaces the tail lamp assemblies entirely. The part no's cited in the link are the parts for the M3. I don't know about the standard E46 -- They have orange corner lenses, so I assume they have a different part number -- i dont know if the m3 tails will fit on the standard e46 -- i assume they will.

                              how would i go about building "scrolling" LED turn signals like the one in the animation i made below? I've seen these on a few newer model cars and on some transfer trucks. I know i'll need some LEDs and i assume a sequencing controller board of some kind, but i don't know exactly what i need, or where i would get it.

                              thanks, in advance.
