I of course have upgraded the lighting system, new larger guage wires for high beams, larger ground wires and have the Classic Retrofit fuse panel which has built in headlight relays.

No significant difference between high and low but both are a HUGE improvement from my old H5 lamps.
I work late sometimes and night time driving is now so much better.

Rennline LED light pattern notch
Hi all
I'm in the process of installing the Rennline LED kit in my '88 Carrera but have two concerns regarding the subsequent light output and pattern. I say process because I'm running without reflectors and lens until I decide to keep them. After a couple adjustments (per Rennline's suggested video
) and nighttime runs I too questioned the improvements. Without a doubt output is superior - white, bright light and wider throw (wonder how this impacts pedestrians) but I was expecting a longer throw. Aside from that I'd appreciate other's thoughts on the following:
1. Referring to the first photo below, after adjustment, there's a notch in the cutoff shadow towards the left. It's disconcerting to these older eyes but perhaps its just a matter of getting use to it? Is this trait common with all the retrokits? Also I was expecting to see a hot spot in order to set horizontal adjustment. Without that, the side adjusters don't seem to change things much.
2. After a couple different adjustments per video instructions, from the 2nd photo taken over windshield it seems I've got adjustment wrong, at least on one side with lots of shadow in left foreground and a bright hot spot on right. Granted most of this foreground stuff is not such a factor from drivers seat. After first adjustment, with cutoff set at recommended 2" below my 26.5" projector height, the range seemed too low so I readjusted upwards to the 26.5" height. That improved things and does not seem to blind oncoming cars (at least nobody flashing me yet).
3. The last photo, taken straight on which may not be a good indicator, seems to show similar output patterns as photo 2, brighter on passenger side unit while driver's side is less. Of course maybe once installation is completed with reflector surround and lens, a lot of these concerns will go away.
Thanks,
Larry
