So this is a bit of a re-hash of the "double special rule stacking question" but I think it's a little different because of how the sabre weapons battery is worded.

The relevant rule in question:

"If this model has a defense searchlight, at the start of each shooting phase it may select a single enemy model within 48" and within line of sight. One friendly REGIMENT unit that attacks the chosen unit adds 1 to any hit rolls until the end of the shooting phase."

Clearly these "markerlights" are spent like 7th edition Tau (used only for 1 unit and only on one unit) but can a unit benefit from 2 of these effects if I have two Defense Searchlights that I put on the same unit, giving me +2 to hit?

Love how other armys are getting tau tricks that they lost......

The core rules state that all modifiers are cumulative. It doesn't seem like searchlights have an "at least one" type clause for the +1 bonus, so it looks like by RAW you can stack them.
