UPDATE:
Ok, so I was so impressed with the performance of these bulbs, I bought a 2nd set for my 1979 Land Rover Series III. It uses the fairly common 7” round headlight unit.
It currently runs Wipac aftermarket lenses and stock 55w/65w halogen H4 bulbs (in itself a big step up from the sealed beam units that were factory fitted).
Removal of old units. These lamps sit in bowls, not loads of room back there. Hoping there is enough air flow too.
First hurdle, the LED bulbs seem to have slightly larger flanges and don’t sit in the recesses fully.
Quick bit of trimming with a pocket knife and they fitted a treat.
Almost impossible to tell they are in there with the lamp off.
No other fitment issues noticed.
I did take some pics of the units working outside of the housings. Dip/low beam uses the two leds under the little sheilds.
While main/high beam uses all 4 LEDs. The big advantage here is, you don’t loose the low beam profile like you do with a halogen H4, which doesn’t illuminate both elements at once.
Low beam cut off, it looks better in the pic than maybe it is in real life (wall shot to follow later on). It certainly isn’t bad, but maybe not as good as the Impreza’s. These lamps uses a smooth reflector and a focused lens to generate the beam profile. So I don’t know if that makes a difference.
That said, the spill around the cut off is full of shadows and dim. And having gone and stood in front of the vehicle with the lights on, it produces very little glare. So as far as I can tell the beam profile is good and safe and not dazzling other traffic.
Main beam is very good.
If I had to make any observations with the 7” round lamps. These LED bulbs are still an upgrade and an improvement. But to a much lesser extent than they were in the Subaru. These Wipac units worked very well with stock bulbs and were probably better than the Subaru lamps, even with Nightbreakers fitted.
The LEDs seem less of a jump for the Land Rover, but still a good improvement. Although the beam pattern doesn’t seem any smoother with the LEDs.
Also oddly the tint seems less harsh cool white. I don’t know if this is just due to a different LED batch, or more likely the focusing lenses of these lamps have maybe caused a tint shift.
They still get the thumbs up from me however.
