There are vey few mods that use LED's that i'd say were decent, the majority og them being a bit too chavvy for my liking but the one i have just done I feel is justified and indeed excellent looking. In the top of your drivers door panel is a 3mm red LED for indicating the status of the alarm system, I live in a rural area with no street lights but I still find it difficult to see if I have locked my car before I go to bed by looking out of the window. Not any more! I have changed the red LED for a pure white ultrabright LED and now I can see it easily. I have an ebony black paintjob and black interior so the white LED looks well flash. And the mod only cost in total £2.50, and this was for the cost of the door panel clips from Audi, the LED I already had but they are only pence in their component form. Try it, you might like it!
