I've got the OEM GM Brazil reflectors on my K1500 Suburban (manufactured for GM Brazil by Arteb:
https://www.arteb.com.br/catalogo/?pa_veiculo=silverado ). These illuminate the road like a European "E-code" reflector.
I actually have two pairs of these, one on the Suburban and another on the shelf as a back-up.
Pictures of one of the reflectors are attached.
The low-beam has a broad horizontal pattern with good visibility into the ditches, with a sharp vertical cut-off to mitigate blinding of oncoming traffic.
The high beam has a very pin-point "spot-light" pattern, so the 4-high mod makes for a great set-up.
