Tyre Pressures

Check your tyre pressures regularly, otherwise you may:

1. Decrease grip on the road (and make steering less precise)
2. Increase braking distance
3. Increase fuel consumption (by increasing rolling resistance)
4. Potentially reduce the lifespan of your tyres

Tyres should always be checked regularly and more so before long journeys.

What is a Multifaceted Reflector Light Bulb?

Multifaceted reflector (MR) is a reflector housing format for halogen as well as some LED bulbs. They are designated as MRXX where the XX represents an eight of an inch - so MR16 means 2 inches, MR8 is one inch. The MR16 was first sold in 1965. GU10 (G=Glass) is a derivative of the MR housing where the U refers to a U-shaped ceramic base mount.

As with all halogen lamps, MR lamps produce significant heat. For GU10 fittings. you can have GU10 halogen as well as GU10 LED.

IP44 and IP65

IP44 is a common designation for lighting.

4 - as the first digit means anything smaller than 1mm in size will not get through the membrane.
4 - as second digit means resistant to water splashes.

IP44 cannot be used when there is exposure to water jets (but not high pressure or high temperature water jets)

IP65 is the recommended minimum requirement when water jets are involved.

Bulbs without IP markings are by default IP20 which means protection from solid objects but no protection from water.
