Honestly theres no need... As a few of us have said, this is what those type of lamp do at the end of their life, grab yourself a couple of replacements (size will be on bulb)
Is that an e27 thread ?if so you can get led lamps that will fit though it does involve bypassing control gear,an easy job,lamps expensive but less than new fittings & labour.
Had this issue years ago on a old mod building and it was caused by individual photocells in the fitting reacting to light from other fittings switching them off and on as each light heated up and changed lux levels. If possible try disconnecting photocells and see if lights stay on just do a couple as test and go from there
