DRL daylight running lamps

[clayt74]

i was planning on getting a pair of the bikevis bullet led lamps for winter, when i stumbled across this site
http://www.dadrl.org.uk/motorcycleinstructor.html

he has the very that daytime lights even dipped beam can be a bad idea???
anyone else got any views on this?

also if i get and fit the leds i was intending on having them permantley on, including with high beam. would doing this be illegal or cause problems with MoT?

cheers
