Japanese light trucks would not be suitable for my line of work

I like personalising my van. I have a few obligatory air fresheners here and there, a mobile phone holder and I even have my own mascot in the form of an orang-utan I bought on a holiday to Cornwall one year. For your information, his name is Vince and he is not a toy.
However, I wouldn't go so far with my personal tastes that I would render my van unsuitable for the road – that would be a waste of the money I spend on van insurance, and not to mention incredibly impractical.
Owners of trucks in Japan don't seem share the same concerns as me though – I recently saw some pictures of a selection of very extravagantly decorated Japanese light trucks.
Enthusiasts gather once a year to show off their heavily adorned vehicles, and the trucks are decorated with so many light bulbs that they have to be powered with a separate generator. Fans can't admire the handy work for too long though, the bulbs are likely to overheat after being on for 20 minutes.
The trucks reportedly cost around £100,000 each to decorate, and many feature extravagant illustrations, collections of toys and even carpeted interiors. The dazzling nature of the vehicles means that they are not legal to drive on roads unless the lights are switched off.
I'll admit it, my van strikes a stark comparison to these monstrosities, but at least I haven't bankrupted myself in attempting to make it stand out from the crowd!
