It's understandable why you would want to upgrade your headlamps, but you're going about it in an unsafe way. Please change your plans and do it the right way -- for your benefit as well as everyone else you share the road with. Also please keep in mind that the lighting modifications/products you're asking about or recommending are illegal.
Rule 11 of this board prohibits advocating illegal activity.
TYC's assurances are not credible, nor based in fact. Their stuff is (objectively) still grossly inferior to genuine lamps. But I have to ask what other response one could reasonably expect from a manufacturer of inferior knockoff junk! Think about it for a few moments: one couldn't reasonably expect to ask a manufacturer of cheap knockoff parts "Hi, does your stuff still suck?" and expect anything other than "Oh, no, of course not! Our stuff is great!". So I'm not sure what the point is of even asking in the first place.
Even more importantly:
DO NOT RUN HIGH-WATTAGE BULBS of any brand. Doing so is not only illegal, but also guaranteed to melt down your new headlamps in short order, and extremely dangerous due to illegal levels of glare no matter how you aim the lamps, poorly-focused beams, electrical system damage/unreliability from the low-quality electrical components you have in mind).
And even if you were looking at standard-wattage bulbs, CEC is not a quality product. It is cheap, poorly-made junk with filaments nowhere near where they're supposed to be (=thoroughly destroyed beam focus). This is stuff you cannot see or evaluate with the untrained naked eye. It takes proper test equipment. However, the safety degradation is very real. That goes for the modifications it sounds as though you made to a truck of some kind, too.
There are two (and only two) 9007 bulbs you should consider using: the
Philips Xtreme Power or the
GE Night Hawk Platinum.
Relays and heavy-gauge/low-loss wiring are an excellent idea, but putting in off-brand (e.g., "Putco") parts means sooner or later, at random, your headlamps will fail while you're in the middle of needing them. This is not a smart or safe way forward. KD and Putco are far from the only choices; good-quality harnesses (and good-quality components to make your own harnesses) are readily available from various reliable vendors.
Finally, to answer your initial question in this thread: do not remove the bulb shields. Alaric Darconville has provided exactly the right explanation.
