A friend of mine has bought this car alarm system:

He wants to connect the auxiliary output of the alarm to the lights, in order for them to flash I guess.
The problem is that the AUX output is only 0.5V high (It's not written on the site, but I believe him). How can I control a 12V voltage with only 0.5 volts?
He thought of a relay at first, but I don't think that there's a relay that switches on with only half a volt.
My thougt is to use a transistor to activate the relay, or a power transistor to replace the relay altogether. However, I don't have any schematics in mind.
Any thoughts or recommendations?
