Troutman Posted June 13, 2007 Report Share Posted June 13, 2007 Agreed, definitely worthwhile for future bulb purchases involving higher priced or hard to install bulbs. I don't know if it could be easily installed for instrument cluster bulbs though. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted June 13, 2007 Report Share Posted June 13, 2007 Lexus is a piece of shit and its "worlds first" led headlamps clearly haven't happened as the new Audi R8 just went on sale. I'm so impressed with the technology that I'm very seriously considering that instead of getting the cls63, the m6, or the 99 360f1 that I sell the M3 and use the extra to fund the R8....LED headlights, R-tronic, magetic ride technology...

enginph Posted June 27, 2007 Report Share Posted June 27, 2007 If its the CEL i have no idea.. The blue 94 LED in my instrument panel is now flickering repeatedly. Anyone know why? Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted June 27, 2007 Report Share Posted June 27, 2007 which bulb, exactly where. certain parts of cars have different voltage, this is why led guys go back and forth in rage about resistors and what not. for example in my jeep, there is a single bulb socket that I will go through 4 in a year, but never once change anything eles. or it could just be a lose bulb Quote Link to comment Share on other sites More sharing options...
Cyberdyne Posted June 27, 2007 Report Share Posted June 27, 2007 Usually flickering means it is on the way out. Little can be done to prevent it except somehow wiring in an Autolumination LED protector when you replace it with one of their 3-LED #74s.

Frankzao Posted June 27, 2007 Report Share Posted June 27, 2007 It's the one to illuminate the fuel gauge. I could be wrong about the size #. I do not think it is loose b/c it flickers when the car is off and not moving even. Quote Link to comment Share on other sites More sharing options...
mattlau89 Posted June 27, 2007 Report Share Posted June 27, 2007 quick question. i changed all my interior lights inside and most of them blew or start blinking. do you guys know why this is happening. and these arent cheap lights Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted June 28, 2007 Report Share Posted June 28, 2007 indeed frank, the fuel/temp is a #74, and that is the first socket to fail in the millenia usually. Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted June 29, 2007 Report Share Posted June 29, 2007 the light in that area of hte cluster, the electrical load is different. all cars have it, just a question of finding where. Quote Link to comment Share on other sites More sharing options...
Frankzao Posted June 29, 2007 Report Share Posted June 29, 2007 find what EXACTLY? Quote Link to comment Share on other sites More sharing options...
Synesthesia Posted June 29, 2007 Report Share Posted June 29, 2007 The bulb which contains a higher load by design and/or lack of resistors. It will be the first, and usually only led bulb to fail. Quote Link to comment Share on other sites More sharing options...
Troutman Posted June 30, 2007 Report Share Posted June 30, 2007 Common causes of Premature LED Failure * Switching on the ignition & starting the engine while the leds are switched on. * Changing or disconnecting the battery while the leds are switched on. * Charging the battery with an auxiliary battery charger, or revving the engine hard with a weak or dead battery while the leds are switched on. * Using jumper cables while the leds switched on. * Excessive AC voltage due to damaged diodes in the alternator. * High system or circuit voltage. * Voltage surges caused from switching on and off amplifiers or other peripheral add on devices that use a lot of power. * Faulty or out-of spec. voltage regulators.

enginph Posted June 30, 2007 Report Share Posted June 30, 2007 Nope. The only reason is that the guy who designed the LEDs didnt consider those issues before and he has to make something up to convince customers. actual reasons: - high temperature mostly caused by high current (or voltage). - High current causing nonrecoverable breakdown - High reverse current (unlikely) - Physical damage (dont try to break them) The thing is they wanna make them f.ing bright and push the current to the limit and they suppose the voltage is 12V but it is 14.4V for milly at least. That makes premature LED failure... Those wont damage LEDs: Switching on the ignition & starting the engine while the leds are switched on. * Changing or disconnecting the battery while the leds are switched on. * *revving the engine hard with a weak or dead battery while the leds are switched on (that directly means poor LED circuit design). Common causes of Premature LED Failure * Switching on the ignition & starting the engine while the leds are switched on. * Changing or disconnecting the battery while the leds are switched on. * Charging the battery with an auxiliary battery charger, or revving the engine hard with a weak or dead battery while the leds are switched on. * Using jumper cables while the leds switched on. * Excessive AC voltage due to damaged diodes in the alternator. * High system or circuit voltage. * Voltage surges caused from switching on and off amplifiers or other peripheral add on devices that use a lot of power. * Faulty or out-of spec. voltage regulators.

///BHRpowered Posted June 30, 2007 Report Share Posted June 30, 2007 Yes and no. and "led" itself is very very tough, HOWEVER, the bases that the leds and mounted into are not as tough, so when installing you have to be careful not to push on the actual led. All cars have these problem, also the leds are designed for 12v, but your car doesn't produce 12v, the battery does, but the alt puts out 14.1-14.4. leds are much more sensitive to load then filiment bulbs. all cars will have this problem. On the millenia its the fuel far right, on jeeps its the oil battery gauge far left, on a bmw its the middle for the tach, on an r8.......

///BHRpowered Posted July 1, 2007 Report Share Posted July 1, 2007 keep several on hand, I would replace it now, being careful when installing. also, keep the leds on full, led's really don't like dimmer switches Quote Link to comment Share on other sites More sharing options...
Frankzao Posted July 4, 2007 Report Share Posted July 4, 2007 It is on full. I suppose I should not drive with the light on all the time. Quote Link to comment Share on other sites More sharing options...
enginph Posted July 4, 2007 Report Share Posted July 4, 2007 Why is that? The lower the current the better for the LED.. also, keep the leds on full, led's really don't like dimmer switches I dont believe it is the LED itself that causes blinking. An LED is either dead or good. I burned lots of LEDs on my senior project.. If I designed LED for cars I would assume the voltage is 15V.
