Narrative:

During landing rollout on runway 22R ord, I noticed the lahso lights flashing at the intersection of runway 27R. I needed to increase braking to prevent going through the intersection. Lahso operations were not, repeat not, in effect. Ground later mentioned the lights were being tested. Further discussion with tower revealed that this may happen often. Either the fact that the lights are being tested and can be disregarded, bad idea, or the lights should be off. They should only be on when lahso is actually in operation.

Narrative: DURING LNDG ROLLOUT ON RWY 22R ORD, I NOTICED THE LAHSO LIGHTS FLASHING AT THE INTXN OF RWY 27R. I NEEDED TO INCREASE BRAKING TO PREVENT GOING THROUGH THE INTXN. LAHSO OPS WERE NOT, REPEAT NOT, IN EFFECT. GND LATER MENTIONED THE LIGHTS WERE BEING TESTED. FURTHER DISCUSSION WITH TWR REVEALED THAT THIS MAY HAPPEN OFTEN. EITHER THE FACT THAT THE LIGHTS ARE BEING TESTED AND CAN BE DISREGARDED, BAD IDEA, OR THE LIGHTS SHOULD BE OFF. THEY SHOULD ONLY BE ON WHEN LAHSO IS ACTUALLY IN OP.
