very good product, log lasting
Makes my Christmas tree sparkle!! Love them. Great inexpensive product and fast delivery. Thanks.
What a difference a little bulb makes. My tree is so nice now with the lights flashing.
Making my Christmas lights twinkle was easy.I used the special red tipped blinker bulbs to replace the first and last bulbs of every light string. These are no ordinary blinker bulbs. I put three strands of multicolored lights on my tree each using the red tipped twinkle function light bulbs. The bulbs control the speed of the blinking. In this case, the two segments of every light set blink on and off In a random fashion. These are just like red tipped blinking bulbs, but they make the lights have a p!easing twinkle effect when plunged in. I will order bulbs like this again to make additional lights twinkle.
Even after Christmas the lights go on/off (blink/twinkle). I will order more of these special blinker bulbs in the future!
This is the best product in the world!These are long lasting twinkling replacement bulbs with red tips.I made my multicolor christmas lights twinkle/flash in one minute. I will order from you again!
