I've been running the Hella E codes for several years now and while they are an improvement on the stock sealed beams, I have had an issue or two. I originally ran them with the standard Hella bulbs that came with them. After a few years, I put in a set of cheap LED H4 conversion bulbs from Amazon that I've still got in there and I'm not really that happy with. The main problem I've had with the Hella lenses is that they've got a foggy film on the inside that I've not been able to get cleaned out other than a small spot in the center. No idea what causes that but it started with the original Hella halogens.
The LED bulbs throw strange patterns and as originally installed, the high and low beams seemed to be swapped around. I swapped the wires on the plug to feverse them which kind of fixed the problem, but on high beam it does seem to hunting possums up in the trees while on "low beam" they cover about the same area as the stock fog lights do.
For the folks who have been using the Toyota lights long term, how are they working out for you? Any issues pop up along the way?
I did order a set last night from some Toyota place in Kansas, which even with the crazy shipping price, was cheaper what I paid for the Hella setup back when I first got the LJ in 2019. I'm planning on leaving the LED bulbs alone once I get the Toyota lights installed. I might go to the higher wattage H4 bulbs after I've run the ones that come with the Toyota lenses for a while.
