Is it an upside-down Blue triangle - Solid

or is it an upside-down blue triangle with the arrow going down the middle pointing down?

It is a blue triangle. It does not matter which way up you have it.
If the battery is fitted with a cut out switch the blue triangle has a red spark across it.

I've seen an upside down and right way up solid blue triangle , plus one with a lightning type jagged line in the middle of it . I thought the reg's normally just said a blue triangle to indicate the position of the battery ....

The blue triangle is to show the location of the battery.
The blue triangle with the red spark is to show the location of the cut out switch.

thanks fellas,
