Basically the mains transformerless LED control circuit is designed around the fluorescent lamp dimmer control IC IRS2530D. The circuit diagram shows how the IC has been wired up and how its output has been modified for controlling LEDs in place of the usual fluorescent lamp. The usual preheating...

One for each led bulb resolves after glow when led bulbs is supposed tro shut off. The equalizer must be spliced across the - ground wire and the + wire feeding to each led bulb. One for each side marker or headlight resolves bulb-out warning problems. ...
Whilst holding the LED in the pliers put the LED bulb into the 5mm hole in the MDF board as shown in the picture above. You may need to clearance the 5mm hole a bit at the top to ensure the Pliers lay flat on the MDF. Bend the LED leads around the drill bits in turn to form ...
In my opinion, a flashlight bulb that lasts 100 hours is a huge improvement and cost saver over the incandescent alternative which gives only 15-20 hours before it dies. You must use some method of limiting current to your strings of LEDs. The easiest is simply using the right number of ...
2.1Circuit Diagram LED Car Bulb Design The image below shows what could be a car LED lamp directly replaceable over the existing holder. It shows a decent looking arrangement of flat, tiny SMD LEds in a circular pattern for enabling optimal distribution of light via the enclosed hind reflector...
Solder a 47Ω Resistor to the cathode of each LED. If you are unsure of which side is the cathode, remember that the LED's cathode side will have a flat edge on the bulb and a shorter leg. Clip off the excess leads between the resistor and cathode using the flush cutters. ...
If switching from an incandescent bulb to an LED taillight, you may encounter error codes, rapid blinking, or static amber lights, these are common due to the low current of LED lights. So, we need to increase the current. Fix this by adding provided resistors into the circuit in parallel...
Step 4: The Bulb Stick the circuit into the bulb and use some hot glue to hold it in place, be sure to have some cold water, you will burn you fingers. Try to center the LED in the bulb. Once you have the circuit in place, bend one of the leads over the base and secure it ...
