Re: led high /low H4 replacement.
Hi JC,
The main problem with LED H4 replacements is that you have to make sure the hi and lo LEDs in each globe are positioned in the same dimensional location as the filaments of a standard globe. You also have to make sure there is some sort of directional shield around the lo LEDs as there is in the standard filament globes. If neither of these are done with the LED replacements then the reflectors of the headlights do not give the same cutoff or directional pattern as they were designed for.
Another thing to watch out for is that some LED replacements while having the directional shield around the lo LEDs, they are made for the US market which drive on the other side of the road so the light pattern is skewed to the right instead of the left.

Re: led high /low H4 replacement.
Having tried MANY H4 LED globes in motorcycles (only one headlight, so it's super important), the only ones I have found that work for true high/low with a proper beam pattern, no 'spill' to blind oncoming drivers, are the new Philips Luxeon LumiLEDs.
Nothing without a 'hood' on the low beam works, they just spray light everywhere and have dark spots. If the LED emitters are not physically in the same place in the headlight that globe filaments would be, they don't work.
As I couldn't really afford those, and unlike the bike where current draw is a problem, I can say the Narva '130 Platinum' in my T30 headlights, are just 'OK'. I now have headlights as good as my GF's 1992 Corolla! Got them on an eBay sale from an Australian 4wd shop for $54.
I don't do anything with a fan, cause when, not if, the fan fails, your expensive LED globes will cook and die. In a car or bike that goes into dust and water crossings, fans are just crap.
If you want really good lights, try to find some xenon HID projectors. I have seen them in overseas T30's and my Japanese domestic imported Pathfinder has them. There is no comparison to H4 headlights in standard R50 Pathfinders...the HID projectors are just freakin awesome! Just make sure the ballast comes with the headlight, as they don't work without it.
I have read here that there was no T30 factory HID lights, but I am sure I have seen them, and I might be able to find the Nissan part numbers which will make finding some easier, but you're going to be looking at anything from $300-$600 per light. Here is the back of one with a factory ballast fitted: (eBay item 172970418929)
There are UK aftermarket ones around as well. Also $$$.
