R2 car bulbs – how to choose the right lighting
The R2 is a bulb for older headlamp designs, found in some classic and older vehicles. The R2 marking identifies a particular bulb family, but fitment also depends on the lamp and vehicle manufacturers' specifications.
How to choose an R2 bulb
Check the old bulb marking or your car manual. Compare the lamp holder type and original electrical system requirements. Do not choose a replacement based solely on its appearance; for kits, verify the exact bulbs included.
Safe replacement and use
Turn the lights off and let the bulb cool before changing it. Fit it properly in the headlamp, avoid touching the glass with bare fingers when prohibited by the manufacturer, and use only approved light sources. Check operation and alignment afterwards when required.
