I had the same problem and bought these: 2015 newest 78mm LED R7S light 6w 360 degree beam angle J118 R7S lamp replace halogen lamp 118mm 135mm 189mmAC85 265V-in LED Bulbs & Tubes from Lights & Lighting on Aliexpress.com | Alibaba Group

It's not the prettiest solution, but does work wonders. If you have enough time for these projects I would consider replacing the fixtures.
