Narrative:
I was in cruise at 9;500 ft. When both left and right hydraulic flow lights started to flicker. I started descending and started heading toward ZZZ. I referenced the QRH running though the left/right hydraulic flow light illuminated checklist. Told ATC i was diverting to ZZZ. On the right midfield downwind I decided to put the gear down. With the gear handle down I only had the two main gear lights green with no nose indication. I referenced the landing gear will not extend hydraulically; trying the press to test and then trying to change the nose gear bulbs with no luck in showing a green indication. I blew the gear down per the QRH procedure; I heard a thump of the gear going down but only had an indication of the left main gear down (green) I continued the checklist by checking the gear warning horn and it did not sound. At this point I [requested priority handling] with ZZZ tower and requested the firetrucks. I referenced the QRH checklists landing with defective main and nose gears and told the tower I was ready for landing. I followed the checklists killed the engines and landed on the good wheel. All 3 gear were down and I stopped on the runway. Hydraulic fluid was all over the right engine. I requested a bus for the 2 passengers and a tow back to the gate. I received clearance from on call duty manager before allowing them to tow the plane to the gate. Cause: hydraulic leak/problem and gear indication problem.

Title: Pilot reported a hydraulic system failure that resulted in a diversion.
Narrative: I was in cruise at 9;500 ft. when both L and R HYD Flow lights started to flicker. I started descending and started heading toward ZZZ. I referenced the QRH running though the LEFT/RIGHT HYDRAULIC FLOW LIGHT ILLUMINATED checklist. Told ATC i was diverting to ZZZ. On the right midfield downwind I decided to put the gear down. With the gear handle down I only had the two main gear lights green with no nose indication. I referenced the LANDING GEAR WILL NOT EXTEND HYDRAULICALLY; trying the press to test and then trying to change the nose gear bulbs with no luck in showing a green indication. I blew the gear down per the QRH procedure; I heard a thump of the gear going down but only had an indication of the left main gear down (green) I continued the checklist by checking the gear warning horn and it did not sound. At this point I [requested priority handling] with ZZZ tower and requested the firetrucks. I referenced the QRH checklists landing with defective main and nose gears and told the tower I was ready for landing. I followed the checklists killed the engines and landed on the good wheel. All 3 gear were down and I stopped on the runway. HYD fluid was all over the right engine. I requested a bus for the 2 passengers and a tow back to the gate. I received clearance from on call duty manager before allowing them to tow the plane to the gate. Cause: HYD leak/Problem and Gear Indication problem.
