Prefect Grade Crossing Lights

These flashing red LEDs are small enough to fit into any manufacturer's grade crossing signal. Great deal in my eyes. Thanks.

custom led's

The custom made led's were for a non typical project that turned out great. So much better than the c7 bulbs it came with. Thanks again !!!

First order to Evansdesigns.

VERY-VERY PLEASED WITH MY FIRST ORDER. Large selection to choose from,which helped make my project "custom". Colin was also very helpful. He reached out to clarify (on the alternating circuit) which colors were to be on/off together. Also he offered a suggestion on color choice, since I choose colors he felt might be bright and dim together. VERY helpful and pleased. Nice small units- no bulk. Best of all - order came in very quickly. I will definitely look at their products in the future.

Well done, excellent Customer service values

I bought a bunch of different circuits from Evan designs, the first time I ordered was maybe 18 months ago, I had told them at that time that if I liked their product I would become a fregular customer. I had some health issues and was did not build anything requiring light circuits like they build and sell. I am back building and I have just purchased nearly 180.00 in different light circuits made to order. I was expecting a 7 to 10 day period for them to build the circuits and then 3 to 5 days shipping. WELL was I surprised they had the order out to priority mail writhin 48 hours of my purchasing, I ordered mid-day Sunday, I had the product in hand within a weeks time, actually I think it was Thursday’s mail that I recieved my order.

As far as customer service I made one phone call to verify that they were still in existence, I spoke to a very kind, courteous, and friendly young lady. I had several questions about what they could and could not do with the light circuits. She was able to answer my questions, both technical and general. AI went to their page and with the knowledge she had supplied I looked at the builds I was working on ?( an RC truck that closely resembles a friends off-duty personal F-350 regular cab S.R.W. With more lights than God should allow, he uses it when working extra jobs. Without the excellent lighting aLED light circuits that Evan Designs produces I would have had a really hard time matching the lighting on this truck!

Awesome lights work great , just wish i had the option of size led 1.8mm 3mm or 5mm would be great

Crossing flashers

Instead of using the circuit as a railroad crossing, I opted to get only two 3mm cool white LEDs to be used as ditch lights on a scratch building project. Evan Designs did the modification of the order for only a couple dollars more. They flash at the rate used on ditch lights and work great. Since I don't use DCC on my layout, it was an inexpensive way of lighting the front of my locomotive which runs on either AC of DC current.

Flashing light relay

Works exactly like you said. Another well made product and worth the money. Two wire hook up and done.

Joe Formato
Works great!

Function and appearance exactly as advertised.

Perfect for older police cars

I use alot of these for the older style police cars that used the "wig-wag" style flashers.

People who order a car from from me love the look and authenticity it adds to thier cars. The best part of it is these guys can make any color combination you wish... A really great product....

Work Great!

The twin alternating LEDs assembly works GREAT!!!
The space available in the cab of the F3 locomotive (G Gauge) is actually quite small compared to the overall size of the unit. Your small wires and compact controller made installation easy. Due to some problems with circuit board that control the directional lights and sideboards, it took much longer than expected to complete.

It’s finally complete and works exactly as I want!!!
Due to a health issue, it will be a while before I can run the F3’s. Will send pics when I do.
I did check out the other items, they are going to get installed soon.
I’m completely satisfied with your products and your willingness to modify them for a customer's needs.
I’ve talked to several of the members of my club (Arizona Model Railroad Society) about Evan Designs and directed them to you.

Thank You it has been a pleasure doing business with you!
