try this rob ....if you want flashing lights on the van then you will need to take a pic with them on as you need to have two pics so it can loop between the two ...

not bad for first attempt

don't know how to line pics up .. but not bad

Was that from the link i posted up rob ? .....not bad indeed   

yes mate .. was hard getting the pic from same angle using my phone .. don't know how to centre an image . thats why it looks like its jumping up and down

Its not its lifting as you rev it stands out more whole pic moving or is that just my thought

The only way you can do it is either do camera burst/multishot and have someone turn the lights on for you or set up a stand so its exactly in the same place ..... i think it looks ok anyway .
