Rear Lights

[avensis02]

Decided to do something different with the avensis in terms of rears lights. Bought myself 2 standard park light rear bulbs and changed these in for the two rear fog light bulbs. A t first i just did it for the laugh to see how it would look and as it's Summer i decided to leave them in until the fog hits anyway was just wondering has anyone else done a bit of home modification to their lights or did this themselves and also is this illegal?

Thanks for yer time
