Preserver your 12v battery life with these led bulbs for your caravan
G4 surface mounted diodes.
Very cheap and only use 0.9watts instead of the usual 10 or 20 watts that a normal halogen bulb would use.
If you go on caravan rallies and use your battery all the time instead of using an electric hook up then your biggest drain on your battery is your lighting.
Fit these new led bulbs into the same sockets as your exisiting halogens and you increase your battery life, immensely.
Let me know how you get on if you buy some of these.
