There is light at the end of the tunnel! excuse the pun
I got the below email from PIAA this morning:-
This product is in the manufacturing program and should be with us in August, the part number will be H505 so please do keep an eye on the web site as it will be featured there as soon as it is available from stock.
Yes it will be much brighter than the yellow one fitted as standard, it uses our latest LED technology and has a special resistor in built in the unit so as not trigger the bulb failure system as it will use only mille amps.
