Wow, a 40lm H4? 55W halogen H4's put out 1000lm. 40lm are going to be ineffective as DRL's, so you may as well just take the bulbs out.
I have 7440's for corner lights, and they're 465lm / 25W. SBLED's 7440's have 80lm/2W.
Here are some 540lm / 5.4W LED's, which would be tempting but for the price of $20/ea.
