Remember when you do this mod you need to adjust the reflector, or you will blind on coming traffic. The right hand lamp reflector is high beam only doing this mod is a trade off as you will lose high beam performance to stop blinding on coming traffic.
You're better off fitting some like Philips X-tremeUltinon LED bulbs not cheap but they work a treat, or you can try the cheaper GT Ultra I've not tried these myself.
