I have a 1993 945 with TYC e-code lights.
Using the 50 watt Lasfit LC plus H4/9003 which only differs by having a
different plug than the USA models.
I did not have to modify the bulb out sensor.
There's a very sharp high cutoff with the e-code lenses so I don't bother
oncoming cars even with the highs on.

I just got a backup set of "60 watt" Lasfit LA Plus LEDs to have on hand
and they bench tested to 25 watts per bulb, both in high and low mode.
So I'm returning these as not up to specs.
It alternates between high and low LEDs instead of having the low and high
beams on together. It features current/power limiting to 25 Watts per bulb.

The Lasfit LC plus installed July 2021 tested:

Left Hi/Low 40.6/28.0 watts
Right Hi/Low 36.4/23.8 watts

These are about $40 at Ebay or Walmart on-line

Lasfit exceeded their specs on the first set purchased last summer, but
flunked out with their pricier LA Plus LEDs.

I was looking at Hikari's "12000 lumen" set and noted "Fuzzy specifications".
I don't think they had the wattage for each lamp? Is that right?
On-line LED headlight specs are frequently a work of fiction.
(Some are hawking 2500 watt LEDs)
Would you measure the current flow of your Hikari's ?
Do they draw the same current high and low?

You can look at them with welding glasses to see if all of the LEDs are used
or only half are on at a time.

I removed the metal baffle surrounding the halogen lamps.
They can be put back easily, but just block light, so they're staying out.
