Narrative:

Bay approach cleared us for an ILS 27R approach at oakland. The WX as reported and as experienced was VFR with some haze at low level and a horizontal visibility of approximately 5-7 mi. At approximately 4-5 mi out, I could plainly see that the runway lights were to the left of our course. A quick recheck of the approach data indicated that we had set the proper frequencys and inbound courses on both navigation sets and that both sets were indicating centerline on the localizer. My copilot then called the tower for a light check and then, and only then, did the lights come up/on on 27R! Apparently the 27L approach and runway lights were on and the 27R approach and runway lights were either off or turned to such a low intensity as to be virtually invisible! As you well know, the approach/runway lights are an integral part of the ILS system and no ILS approach may be authorized/attempted without them.

Title: CPR SMT PIC'S COMPLAINT ABOUT RWY LIGHT SETTING AT OAK ON RWY 27R.

Narrative: BAY APCH CLRED US FOR AN ILS 27R APCH AT OAKLAND. THE WX AS REPORTED AND AS EXPERIENCED WAS VFR WITH SOME HAZE AT LOW LEVEL AND A HORIZONTAL VISIBILITY OF APPROX 5-7 MI. AT APPROX 4-5 MI OUT, I COULD PLAINLY SEE THAT THE RWY LIGHTS WERE TO THE LEFT OF OUR COURSE. A QUICK RECHECK OF THE APCH DATA INDICATED THAT WE HAD SET THE PROPER FREQS AND INBND COURSES ON BOTH NAV SETS AND THAT BOTH SETS WERE INDICATING CENTERLINE ON THE LOC. MY COPLT THEN CALLED THE TWR FOR A LIGHT CHECK AND THEN, AND ONLY THEN, DID THE LIGHTS COME UP/ON ON 27R! APPARENTLY THE 27L APCH AND RWY LIGHTS WERE ON AND THE 27R APCH AND RWY LIGHTS WERE EITHER OFF OR TURNED TO SUCH A LOW INTENSITY AS TO BE VIRTUALLY INVISIBLE! AS YOU WELL KNOW, THE APCH/RWY LIGHTS ARE AN INTEGRAL PART OF THE ILS SYSTEM AND NO ILS APCH MAY BE AUTHORIZED/ATTEMPTED WITHOUT THEM.
