how to dye my brown hair extentions light red?

my hair is light red, i use shwartzkopf 'infra red' permanent hair dye. I recently purchased some chocolate brown human hair extentions knowing that i could dye them. Unfortunately when i tried, they didnt turn out as light as my hair. Mybe i have to bleach them first and then try the dye but i dont want to damage the hair as they were quite pricey! any suggestions??
