TIGER-PETE now the thread makes sense,depends on which way you want to go,if it is a simple point of upgrading your bulbs,the Phillips Xenon ultra bright,good upgrade from standard and will slot straight in as they are same design,someone on here upgraded to LED it was fiddly and not that successful according to them,then you can go HID,this is the way I would have gone if it was for all the fitting issues,I personally prefer HID over LED,I have had the opportunity to compare in reallife situations HID over LED in spotlights,although LED is a far brighter and more spreading light over a very short distance,HID is very bright and throws light over a far longer distance,this is what I have found anyhow,and to Convert to LED is wildly expensive,HID has become reasonably priced these days,but again due to Ballast sizes,can be involved to fit them
