You can try B & S parts in Duleek and and Summerhill spares for your head lamp, They are both good for bonnets aswell especially if you are going to get it re-sprayed it does not matter what colour it is in. For your head lamp they are normally about 50 euro, make sure you state what side it is for and if it electric motor. As stated there is no need to go to garages for these parts and try and get them yourself as a mechanic will charge extra if he has to go and collectthem for you.
