Just fitted some small low voltage (24v) outside lights to a tree. The
lights are on a single loom and seem to be wired in 4 different circuits
with a "twinkle" bulb in each circuit (distinguished by having a red base).
Tested the bulbs before assembling and they al twinkled fine - takes about
30secs for them to get going.
In order to get the lights in place I needed to splice in an extension
wire - crimped and taped connections. The problem now is that I've lost my
twinkle in all but one circuit. I've tried checking my joints and changing
the twinkle bulbs but all to no avail - the bulbs mostly just stay
All I can think is that I've somegow introduced too much resistance and the
twinkle bulbs are no longer getting a large enough current through them to
heat them to the magical twinkle point ;-)
Anyone know how I can get my twinkle back?

Could it be that it's just too cold outside for your twinkle to perform
properly, but it worked okay in the warm?

Rub gently with a soft cloth to warm it up? Well, it's supposed to work for
If you swap the working twinkle bulb from one set, to a set that isn't
twinkling, does the twinkle move with the bulb, or is it stuck with a
How long is your extension, and is the wire the same thickness, thicker, or
thinner than the original wire?
At last, someone sympathetic to my dilemma ;-)
1. Twinkle generally moves with the bulb but not always - sometime I lose
all my twinkle!
2. Extension is about 2-3 m and is much thicker than original wire (I used
some old mains cable I had).
If it helps, I've been through two sets of spare twinkle bulbs and only one
twinkles in the lengthened cable..
Ok, so the wire isn't a problem here!
How have you actually joined the wires?
Although it shouldn't matter, have you kept the polarity the same (or was
there a plug on the end of the wire before you chopped it that would fit in
the transformer either way?
Have you fitted any replacement bulbs in the set that my not be the correct
bulbs (Or is it a new set?)
I know it is a pain in the arse, but if you bring them inside, complete with
the new extension, do they start to twinkle? - if so, are they supposed to
(The twinkle works by a bi-metallic wire, when it gets hot it bands, thus
severing the connection, as soon as it goes off, it cools, the wire bends
back thus reconnecting the lights again, then it repeats - If the bulb is
too cold, it wont bend enough to sever the connection, so you lose the
Solder will give the best connection, you could solder and terminal block if
Have you tried the suggestion BigWallop made of grasping the twinkle bulb in
your hand to
see if it starts it?(This is a lot wasier then ripping them off the bush or
bringing them inside!)
There's no way I'm untangling them from the tree to play with them this side
of Xmas - twinkle or no twinkle!!
I did try warming the bulb in my hand in situ - but this didn't work.
However, I found that by moving the twinklers further down the line I was
able to get two circuits twinkling - which is better than before and will do
I thought about you tonight while viewing the huge tree at the West
Yorkshire Playhouse which had scores, possibly hundreds of twinkles on it. I
pondered that you might have a bigger problem with something like that.
By the way, I allowed Spouse to read this thread. He wet his knickers, don't
know why ... but he sobered up when he saw the technical stuff and nodded
with approval so someone's doing something right.
And you haven't lengthened any of light strings ? Do they start to twinkle
when you hold the flasher lamp in your warm hand for a minute or two ? Try
putting two flasher lamps in the one light string to see if it brings your
