High and wide is always a problem on the KLR, without resorting to some sort of stalks coming off of the front sub frame. I have seen junque mounted on hand guards and mirrors but, meh.
A couple of neat and clean solutions are the following:
Twin Headlight Ernie offers these brackets for fork mount, https://twinheadlighternie.smugmug.c.../KLR/i-DF4rHQd
. Ernie's business model is a bit different, but he's good people. Contact him via e-mail for ordering.
JNS offers the same thing, Kawasaki KLR650 Auxiliary LED Light Mounts
Bear in mind that the A1 was designed before electricity was discovered and you don't have a lot of overhead left for accessories. Two modest LEDs should be OK, but you'll want to pull power from the starter solenoid and run it through a relay, triggering off of the lighting circuit.
I have brackets similar to these for cornering lights. https://twinheadlighternie.smugmug.c.../KLR/i-wpKKMq9
I think for conspicuity they are OK. . If you are a bit of a fabricator you might be able to gin up something a bit wider that is along the same lines as the two options above. Going with 3mm aluminum sheet or thicker should provide enough rigidity, especially with some horizontal bends for stiffness.
With the Gen 1 bikes a significant improvement to the forward lighting can be had by upgrading the wiring harness to power form the solenoid via relays. Eastern Beaver makes a good one. He's in Japan, but ships quick. He's good people (Canadian), too. H4 Kits
