This guide has been compiled based on my own experiences in carrying out the Discovery light conversion. Whilst it has been carried out to the best of my knowledge, no liability can be accepted by me for loss, damage or injury caused by any errors in, or omissions from, the information given. If you are in any doubt, you should consult a qualified motor mechanic or automotive electrician. Prior to carrying out any electrical work, you should disconnect the car battery but remember that this will affect any radio security code and central locking - do not leave your keys in the car!
