LED Headlights on a 90 Integra, Legal Or Illegal?

The law changes from one state to another, but in California it is the following: Headlamps on Motor Vehicles 24400. (a) A motor vehicle, other than a motorcycle, shall be: (1) Equipped with at least two headlamps, with at least one on each side of the front of the vehicle, and, except as to vehicles registered prior to January 1, 1930, they shall be located directly above or in advance of the front axle of the vehicle. The headlamps and every light source in any headlamp unit shall be located at a height of not more than 54 inches nor less than 22 inches. (2) Operated during darkness, or inclement weather, or both, with at least two lighted headlamps that comply with paragraph (1). (b) As used in paragraph (2) of subdivision (a), "inclement weather" is a weather condition that is either of the following: (1) A condition that prevents a driver of a motor vehicle from clearly discerning a person or another motor vehicle on the highway from a distance of 1,000 feet. (2) A condition requiring the windshield wipers to be in continuous use due to rain, mist, snow, fog, or other precipitation or atmospheric moisture. Added Sec. 2, Ch. 415, Stats. 2004. Effectve January 1, 2005. Operative July 1, 2005. Amended Sec. 9, Ch. 311, Stats. 2006. Effective January 1, 2007. -------------------------------------------------------------------------------------------------- All headlamps, irrespective of State, are governed by standards published and adopted by the Society of Automotive Engineers (SAE) and the Federal Regulations. So if your LED's have a SAE seal on it then they are legal, if no SAE seal then you run the risk of getting a ticket.

From an early age to pursue Enlightenment and from college, to write books passing on the wisdom of the Masters about Enlightenment.Daily meditation leads to Enlightenment, Permanent Bliss, the goal of life. Peace to you!

2. How has appreciation in the dollar led to a fall in gold prices?

The dollar has not appreciated in purchasing power just the opposite

3. How to make simple AM detector using an LED?

My experience is that an LED does not act like a common diode -- that is, it's not much use as a rectifier, or especially as a detector, because it requires too much forward voltage and has too much drop.If you wanted to rectify something like 6 VAC, an LED might work, but when you are trying to detect a few microvolts, it wo not do anything by itself; it will act like an open circuit. Your circuit above may be attempting to correct this problem with a DC bias (which needs to be critically close to, but below the LED's forward voltage drop, so the LED will "switch on" and "switch off" as the incoming RF voltage fluctuates). Beyond that problem, however, once the LED does "switch on", so much of the energy it passes goes into light production that there's nothing left to drive your audio amplifier.If you change the LED to a low-bias germanium diode made for detector use, or zero-bias FET, and alter the biasing to suit the new component, you might get a functional radio (though your single transistor is not well matched to the high impedance of a crystal earphone -- you would be better with a low impedance headphone).As noted in comments, however, if you are attempting to just give a visual indication whether the tuned station is in fact transmitting, you need the output of the receiver to control the LED. To do that, you need to start with a working receiver, in this case, using the original diode specified for the circuit you built. Once you have that, you can experiment with replacing the speaker or earphone with an LED (using the level control to determine when it lights) or a circuit that will drive the LED

4. My Led Bulb will not flashing on my 1988 Ford Ranger?

The original bulb is a "dual filiment" bulb and an LED is not. That is your problem

5. who is making led display for sony?

Last time I checked it was SAMSUNG. And not only displays, I believe they share other internal components as well
