Fast Flashing 2.5 Hz 3mm Square LEDs  fast flash

Our bulb LEDs now come with none of the extra plastic! These mini LEDs are small enough to fit into the tightest spots in your layout and are just as bright as our other lights. At 3.2 mm by 4.4 mm by 2.1 mm, these small LED lights are technically more rectangular, but they give a very modern, square look!

Available in various voltages, these trim and small battery operated LED lights can also be ordered in solid and fast flash.

The square LEDs are very popular with our diecast customers because of their ability to fit into tight spaces, the exceptional amount of light they give off, and the variety of colors and voltages we have in stock.

Remarks apply to this purchase and two others. Products solve many difficulties finding replacement bulbs and sockets needed to maintain my postwar Lionel layout.

Bringing your layout to life

I have purchased several LEDS from Evan Designs. Every purchase brought a section of my layout to life. The LEDS are easy to work with have multi voltages that you can use and are easy to install on emergency vehicles. If you have any questions about their product they answer you the same day if not the same hour. I recommended Evan Designs to all my MODEL RAILROADING friends. One other thing the prices are very reasonable.

Mega square LED

I was sent a replacement LED without asking! I was able to replace the one with the broken resister. I included a picture of my project, a string of square, porcelain lamps.
