What have you had on there up til now, and did they throw much light for you?
Those from "MG Magic" look sort-of period on a Speedster (they're popular on Hot Rods from the 1930's, too) , but the amount of light they throw out ahead is more of a suggestion than a beam. They would be more like the daytime running lights we see on some new cars, today. If that's what'cha lookin for, then go for them - that price isn't bad, either.
If you're looking for a lot more light to better see things up ahead and yellow to boot, then you could search eBay or Amazon for a pair of Marchal amber fog lights or a pair of Hella 500 series:
