FIVE VERY TINY 0402 FLASHING BLUE SMD LEDs WITH 7 INCH PRE-WIRED LEADS.  SMD means they are usually "Surface mounted".  But with the 7 inch leads they can be used as you would any other led or lamp. These flash automatically when lit, without any additional circuitry when using 12 - 16 volts with both male and female sockets provided, or when using the appropriate resistor. They are 1.60 x .80 mm. They're also brighter and last for years longer than an incandescent lamp. Excellent for HO, TT or N scale. They can be used for police cars, fire engines, ambulances, or just about anywhere you might want some very small flashing blue lights. They are 2.8 V to 3.4 V, 15 - 20 ma.  The tiny wires are .028 mm. They can be used with DCC, or your standard 12 Volt or higher DC model railroad with the sockets provided or with the appropriate resistor. Let me know what voltage you're using and I'll include the correct resistor at no additional cost. 

Note:  The anode (positive) lead is red and the cathode (negative) lead is black.?

If you would like more than three just put the number of lots in the quantity box and hit "Buy Now".  The shipping and handling charge remains at $1.00 no matter how many you want.   

Not sure of how to wire what you want?  Any help you might need or questions you might have about voltage, resistance, wiring in parallel or series, etc. we will be happy to answer!

Have you seen our "Constant Brightness Super Bright Locomotive Headlight kit", or our "3 volt 3mm lights with 5 in. leads"?  They're great for lighting up your dark passenger cars without the plastic melting heat of 12 volt lights!  Both available !
