Introduction: License Plate LEDs
Have a few LEDs and resistors laying around. Why not convert your license plate lights to LEDs.
Step 1: Gather the Tools & Parts
White 5mm LEDs (you determine how many to use)
¼ resistors (value determined by how many LEDs you use)
Solder & Soldering Iron
Step 2: Planning...
First you need to determine how many LEDs your going to use. Then use one of the many online led calculators to determine resistor value. Most of the calculators will even make a diagram as how to wire your LEDs.
Below is a link to one I often use.
Step 3: Putting It Together
I only used three LEDs to replace each bulb. The proto board is cut roughly the same size as the bulb that’s being replaced. They are wired in series. I placed the LEDs and resistor on the proto board as to how they would be connected. I then twisted the connections that are to be soldered. Then I tested with a small 12 volt battery I had. Now that I know they work it’s time to solder.
Step 4: Test & Install...
Now just clip the twisted ends you soldered and test again. The positive and negative leads that extend from the end are folded over so they fit nice and snug into the plug.
