Hello again fellow eBayers!

Please read entire description to ensure you get your 12 Free LED's!

If you only need 1 unit there is a separate listing for single item purchase. Select see other items to find listing.

Pictured here is a group of 3 flasher modules manufactured in USA with 2 color coded (red positive black negative) outputs and 9vdc battery lead for power input. Plus 12 free LED's!

You may elect to use a 9vdc or 12vdc plug in transformer to power your module. It is your responsibility to ensure the correct polarity when powering with a separate transformer. Ensure that polarity is correct ! Item can not be returned if 9vdc battery clip has been removed.

You may also elect to add a control circuit which turns on/off your module such as in a track sensor of oncoming train to activate a relay to turn on/off RR crossing signals. These should be tapped into the black power lead from the 9vdc or 12vdc power source. This is your responsibility to determine the polarity and controls you will use. Cutting the black wire or removing the 9vdc battery clip makes the units NOT able to be returned, so please be sure you do it correctly. I suggest wiring with 9v battery first and then adding your controls or alternate power source. I am happy to answer questions.

Also the LEDs are polarity sensitive with the shorter lead being the cathode/negative (black wire), and the longer lead being the anode/positive (red wire). NO additional resistors are to be used. The output leads are paired and cannot be crossed. One LED per output must be used or flasher will not work properly.

Module is set up for prototypical flash rate of railroad crossing signals. Case has double sided tape for easy mounting under your layout. It is recommended to complete your wiring before mounting the module.

A trimmer/potentiometer is mounted in circuit to allow for increase or decrease of the flash rate if you use the flasher unit for animating other layout/diorama needs. 

Simply complete your wiring and mount case with provided double sided tape leaving enough room to be able to open clamshell case. Place small flat screwdriver into potentiometer slot and turn to increase/decrease flash rate speed. 1/4 turn max in either direction.

Animating model railroads adds interest and realism to layouts and other modeled dioramas. Aside from RR Crossings there are many other applications where flashing lights can add points of interest limited only by your imagination.

Here are some projects I have worked on.

Set up a burning building on your pike using red and amber lights to animate the fire. Try using a smoke unit also to create smoke!

Animate the lights on emergency vehicles at the simulated fire or roadside police stops or accident sites!

Animate campfires and barbecues again using a smoke unit to add realism and points of interest!

Animate a flashing red/yellow traffic light for 4 way road intersections!

Use to set up flashing strobe light effect in storefront windows as some retailers do to attract attention to their store!

You will receive 12 free 3mm 20ma LEDs with your order. I have 5 colors available: RED, GREEN, BLUE, YELLOW, & CLEAR (white). To order add module to cart and click request total on the checkout page. Include a note to seller specifying the 12 colors of LEDs you want. Then wait for me to send your invoice.

With this listing you purchase 3 units or multiples of three units. You must add them to cart or change quantity box for the number of orders you want. You must still then click request total on the checkout page and send a note specifying the colors of LED's you want. 4 for each flasher module you order. 1 order choose 12. 2 orders choose 24 and so on.

VERY IMPORTANT NOTE: UP TO 4 LEDS CAN BE POWERED WITH THIS MODEL UNIT. The RED, GREEN, & YELLOW LEDS WORK WELL IN ANY COMBINATION. ALSO THE BLUE, & WHITE LEDS WORK IN ANY COMBINATION. MIXING ANY COMBINATION OF BLUE & WHITE WITH THE OTHER COLORS RED, GREEN, & YELLOW DOES NOT WORK FOR SOME REASON SO PLEASE KEEP THIS IN MIND.

I do accept returns of units which have not been modified in any way! All units are tested before being shipped. Returned units will be tested upon receipt. No refund will be issued if unit is modified or burned out! Since the buyer pays return shipping please take this into account.

Thanks for looking and happy modeling!
