Avoid light clipping withou shadow

Hey guys.
We are on Forward render and target VR. Relatime lights are expensive. We fire off a pointlight a frame or two when our muzzle flashes goes off to create effect, also this gives away the player which is good for balance (Multiplayer). But the light clips walls. Anyway of fixing this without turning on shadows? Shadows are way too expensive in VR, plus you really dont have time to register them anyway because the light is seen for such a low amount of time.

Its mostly a problem for levels were you have multiple floors and the light from fire fights on first floor bleads up to the second floor and vice versa.

We have no problem buying assets etc to fix this, its such a big game breaker.

One way could be to raycast towards player camera, and set the radius of the pointlight to that value. But it feels there must be a more standard way of solving this?
