BASICS ABOUT LED`s
Light emitting diodes, are commonly called LEDs. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.
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, and they last just as long as a standard transistor. LEDs can last a long time, and sometimes a lifetime.
HOW TO WIRE YOUR CAR WITH LED's or NEON's?
First off, there are hundreds of ways your car can be wired. A car is full of electronics and all of these electronics run off 12V DC power. This is the same power used in motorcycles, RV's and other machinery like tractors. All cars have a ground which is on the chassis of the vehicle; this is called negative or ground. So if you are going to wire something you can always hook the negative (black wire) of a led to the metal of the car exposes anywhere. The positive (white or red) needs to go to a 12V+ source in the vehicle. You must understand that LEDs only work in one polarity. If the wires are hooked up backwards they will not light up.
Many of the LED`s we supply are direct fit replacements for the original filament bulbs so you needn’t worry about making an extra power source to supply them as they’re simply plug n play.
If your putting them in a custom location the best way to wire your car is to first find out what you're going to light up. Find the location you are going to mount the leds, and then look around the location for a source of power. For example, if you're going to mount the LEDS under the glove box dash: Find source of power behind the radio. The back of the radio has 2 types of 12V power you could use. 1. 12V+ Power which is always on, usually YELLOW and 2. A 12V+ power called remote (some times RED), which only comes on when you have your car ON. The remote wire is the best wire to use for 12V+ for running interior leds. You do not need to worry about installing switches to turn them off when you're leaving your car.
Other locations for power include your dome lights, which turn on only when the doors are open. You can create some nice led effects in your car if you wire to these. Installation of lights in the engine bay or front bumper can be wired to the headlights or park lamp lights. All you need to do is find which one is 12V+ and which ground. Simple wire to these and your lights only come on when you have the headlights or park lamp lights on. If you do not want to go that route, then you can wire the leds directly to the battery with a SWITCH INLINE. This is going to make things much more complicated because you need to figure how to get wires from the battery inside and create a circuit.
LED TAIL LIGHTS OR BRAKE LIGHTS?
LED tail lights / Brake / Turn signals can be done by wiring the leds directly to your wiring coming to your tail light housing. However, one think you have to understand is, most cars recognize normal bulbs only, and if you hook leds ONLY to this wiring, certain cars will give you issues, such as not working or fast turn signals (like bulb burnt out). For Turn signals you 100% need to follow below:
Solution is to use LOAD LINE RESISTORS. What a Load line resistor is it fools the car in thinking that you still have normal bulbs hooked to the car. Since your trying to used LEDs you must place these resistors to the wiring. Please look below for the wiring. These resistors can be picked up in our ebay shop. You may not need to do this resistor modification if your only doing the brake/Tail light on certain cars. It depends on the car. But the Turn signal you must do on all cars.
TROUBLESHOOTING WITH LED`s
If you’ve purchased LED`S from us and are having trouble getting them working there’s usually nine times out of ten one of two reasons below that’s the cause of this. Please check this before emailing us with your problem as these are both an easy quick fix to the problems you may be experiencing:
Polarity
The majority of LED`s we sell are polarity sensitive meaning they will only function one way around, because LED`s are so small there’s no + and – marked upon them, but if you do and they don’t light up then please try simply inserting the other way around thus to reverse the polarity (+ and -).
Contacts
If you’ve tried reversing the polarity as discussed above and the LED still doesn’t light up the problem maybe be very often down to the metal contacts on the LED being bent out of position. With the LED`s being very small and delicate its easy for the metal contact legs to get bent out of place. Just try bending the out a little for a better connection.
Testing
If you’ve tried both of the above and still not managed to get the LED working then it could be possible that the LED is in fact faulty. The best way to check this is to grab yourself a 9v pp9 little square battery. You can gthen bend the contacts out on the LED slightly and touch it on top of the 9v pp9 battery to see if the LED lights up successfully (try it both ways around).
Brightness
The LED`s we use here at LED auto design are amongst the brightest available on the market today and we use the viewing angles in each kit for each application as they’re required. If you’ve fitted LEDs to your dials / interior and don’t feel they’re bright enough please bear in mind blue led is a much darker colour in the spectrum than the original colour may have been. Also its worth noting that on some vehicle dials the digits maybe black (in the day) with green or amber filters built into them in some cases this can filter out the blue light and not let it pass through so in this scenario you may need to remove the filter or perhaps use a different colour like red which would penetrate the amber filter.
