Goldcross Cycles in Camberwell (VIC) has 22.5% off all bicycle lights they have in stock. I am not sure whether it applies in other stores, or when it finishes (sorry).
The website shows a number of lights with the discounted price, but when I went into the store the sales assistant told me that the discount applies to all lights, and light packs, they currently have in stock.
Example: I bought the Niterider Mako 1/Cherrybomb Combo for $54.21, which is advertised on their website as $69.95 (http://www.goldcross.com.au/online-store/products/Niterider-…).
Their computer did not automatically register the price discount for this light, so they had to manually apply the discount.
PS. I used the lights tonight and they are incredible for the price!
