OK, after a long search on Google regarding high beam and linking up with other sites and forums, I have found 2 possible upgrade solutions, which will increase high beam output.
This is the most cost effective upgrade. Replace high beam bulb 9005 (HB3), with uprated 100 watt bulbs.
I checked wiring and plugs and checked the fuse. The wiring is OK to take on the extra power and the original fuse rating for the high beams at 20A is OK. TBH, you can plug in 10A fuse and still get away without it blowing.
I found a link here although there may be other bargains. Its a pair of 9005, plus comes with 2x sidelights. Its apparently coated which is to help filter some of the yellow but I'm sure the coating will eventually fade off.
This is expensive! but it will get the closest desired effect for a HID solution for your high beams, little or no warm up time its fast enough for a flash.
Parts required, a pair of OEM replacement D4S ballast. Denso has been recommended a few times on various forums and I know of this brand can be found on our cars e.g. alternator and the front wind shield wipers motor. It has a very shortest warm up time, ideal for flash.
Also a pair of AMP D4S harness and a pair of HID 9005 bulb is needed to complete the project. The ballast is the most expensive part, which makes it an expensive mod!!!
For now, I've gone with the Solution 1, so lets see how that goes
But anyone here for Solution 2 I have added a video here of D4S Denso ballast, the igniter is build in and the rest is plug and play.
