I discovered the small blemish in the reflector after dark, so I did not get a photograph. However, I will take a photograph today, and post it in this thread. :)

Thanks Spud for the lead on these bulbs, i placed an order also and the discount code provided is still valid for anyone wondering.

I cut a hole in the back of the RX3 headlight assembly so it is large enough for me to change the light bulb without having to remove the rear cover. I also placed a small hole at the bottom of the headlight assembly to allow for water to escape.

The hole also allows heat to escape the headlight easily, helping to prevent any possible damage to the reflector from using a light bulb with higher power. ;)

That looks like a large hole. Do you have a "before" shot?

eep. He basically took the whole back of the headlamp enclosure off...

The back was totally enclosed, except for the small square where the wires come out of the headlight. ;)

Actually, the great majority of the cover is still in place. The cover is just as strong structurally as it was before. I merely removed enough material to make it easy to replace the H4 bulb when it burns out. ;)

I could have made the hole much smaller. However, I want to be able to replace the H4 bulb without having to remove the entire rear cover of the headlight. ;) Most headlights are entirely open in the rear.

One of the nice things about H4 bulbs is the ability to purchase one at WalMart, et cetera, if the bulb extinguishes while you are traveling away from home. Once I find a replacement H4 bulb, I don't want to fiddle with the 9 screws in the dark, in a parking lot, or alongside the road. ;)

Excellent plan. The heat dissipation can't hurt either.

i like what you've done spud ,,,i didnt make my hole quite that large,but after seeing yours,,i need more surgery!!

:)
I did not enjoy trying to remove the 9 screws in my *garage* so I suppose I should follow suit and subject my headlamp enclosure to surgery ;)
(I installed the H4 bulb last weekend following your instructions and found it very easy to accomplish, except for fussing with the screws :P)

I don't like to mess with those screws, either, even under the most comfortable circumstances. ;)

:hehe:

Using the H4 bulb, the RX3 headlight does a very nice job illuminating the road ahead. I like the large size of the RX3 headlight, and the excellent light pattern it projects when it has a decent light bulb, such as the H4 bulb. :tup:

Incidentally, I used my dremel tool to cut the opening in the rear of the headlight. The dremel tool makes the job very easy. :tup:
